gpc-monetization（GPC 货币化）

gpc-monetization

Manage subscriptions, in-app products, purchases, and pricing with GPC.

When to use

• Creating, updating, or deleting subscriptions and base plans
• Managing subscription offers (introductory, upgrade, winback)
• Creating, updating, or syncing in-app products (one-time purchases)
• Verifying, acknowledging, or consuming purchases server-side
• Cancelling, deferring, or revoking subscriptions
• Handling refunds and voided purchases
• Viewing subscription analytics (active, trial, churn, conversion)
• Migrating subscribers to new price points
• Converting prices across regions and currencies

Inputs required

• Authenticated GPC — gpc auth status must show valid credentials
• App package name — set via --app or gpc config set app
• Product JSON files — for create/update operations (subscription or IAP definitions)
• Purchase tokens — for verification, acknowledgement, and consumption
• Developer account ID — for some purchase operations (--developer-id)

Procedure

0. Verify setup

gpc auth status
gpc config get app

Confirm auth is valid and default app is set. If not, Read: the gpc-setup skill.

1. Subscriptions

A. List and inspect subscriptions

# List all subscriptions
gpc subscriptions list

# Get details for a specific subscription
gpc subscriptions get <product-id>

# Paginated listing
gpc subscriptions list --limit 50

B. Create a subscription

Create a JSON file defining the subscription, then:

# Preview first
gpc subscriptions create --file subscription.json --dry-run

# Create
gpc subscriptions create --file subscription.json

# Specify a regions version (defaults to 2022/02)
gpc subscriptions create --file subscription.json --regions-version "2022/02"

Read: references/subscription-schema.md for the JSON structure and field reference.

C. Update a subscription

# Update specific fields
gpc subscriptions update <product-id> --file updated.json --update-mask "listings"

# Preview changes
gpc subscriptions update <product-id> --file updated.json --dry-run

# Upsert: create the subscription if it does not already exist
gpc subscriptions update <product-id> --file updated.json --allow-missing

# Control propagation speed (default: LATENCY_SENSITIVE)
gpc subscriptions update <product-id> --file updated.json --latency-tolerance LATENCY_TOLERANT

The --update-mask flag controls which fields are updated. Omit it to replace the entire subscription.

The --allow-missing flag enables upsert behavior: if the subscription does not exist, it will be created instead of returning an error.

The --latency-tolerance flag controls how quickly changes propagate. Use LATENCY_SENSITIVE (default) for immediate propagation, or LATENCY_TOLERANT when you can accept a delay in exchange for higher throughput during bulk operations.

D. Batch operations

# Batch-get multiple subscriptions at once
gpc subscriptions batch-get <id1> <id2> <id3>

# Batch-update multiple subscriptions from JSON
gpc subscriptions batch-update --file batch-updates.json --dry-run
gpc subscriptions batch-update --file batch-updates.json

E. Delete a subscription

gpc subscriptions delete <product-id> --dry-run
gpc subscriptions delete <product-id>

2. Base plans

Base plans define the billing period and pricing for a subscription.

# Activate a base plan (makes it available for purchase)
gpc subscriptions base-plans activate <product-id> <base-plan-id>

# Deactivate a base plan (stops new purchases, existing subscribers unaffected)
gpc subscriptions base-plans deactivate <product-id> <base-plan-id>

# Delete a base plan
gpc subscriptions base-plans delete <product-id> <base-plan-id>

# Migrate prices for a base plan
gpc subscriptions base-plans migrate-prices <product-id> <base-plan-id> --file prices.json

All base plan commands support --dry-run.

3. Subscription offers

Offers define promotional pricing (introductory, upgrade, winback).

# List offers for a base plan
gpc subscriptions offers list <product-id> <base-plan-id>

# Get offer details
gpc subscriptions offers get <product-id> <base-plan-id> <offer-id>

# Create an offer
gpc subscriptions offers create <product-id> <base-plan-id> --file offer.json --dry-run
gpc subscriptions offers create <product-id> <base-plan-id> --file offer.json

# Update an offer
gpc subscriptions offers update <product-id> <base-plan-id> <offer-id> --file offer.json

# Upsert: create the offer if it does not already exist
gpc subscriptions offers update <product-id> <base-plan-id> <offer-id> --file offer.json --allow-missing

# Control propagation speed for bulk offer updates
gpc subscriptions offers update <product-id> <base-plan-id> <offer-id> --file offer.json --latency-tolerance LATENCY_TOLERANT

# Activate / deactivate an offer
gpc subscriptions offers activate <product-id> <base-plan-id> <offer-id>
gpc subscriptions offers deactivate <product-id> <base-plan-id> <offer-id>

# Delete an offer
gpc subscriptions offers delete <product-id> <base-plan-id> <offer-id>

4. In-app products (IAP)

One-time purchases — consumables, non-consumables, entitlements.

A. List and inspect

gpc iap list

# Paginated listing (useful for apps with many products)
gpc iap list --page-size 50
gpc iap list --page-size 50 --next-page <page-token>

gpc iap get <sku>

New in v0.9.51: gpc iap list (aliased as gpc one-time-products list) now supports --page-size and --next-page for paginated results. The response includes a nextPageToken field when more results are available.

B. Create and update

# Create from JSON
gpc iap create --file product.json --dry-run
gpc iap create --file product.json

# Specify a regions version on create (defaults to 2022/02)
gpc iap create --file product.json --regions-version "2022/02"

# Update
gpc iap update <sku> --file updated.json --dry-run
gpc iap update <sku> --file updated.json

# Upsert: create the product if it does not already exist
gpc iap update <sku> --file updated.json --allow-missing

# Control propagation speed
gpc iap update <sku> --file updated.json --latency-tolerance LATENCY_TOLERANT

# Delete
gpc iap delete <sku>

Read: references/iap-schema.md for the JSON structure and field reference.

C. Batch delete

# Delete multiple IAP products at once
gpc iap batch-delete <sku1> <sku2> <sku3> --dry-run
gpc iap batch-delete <sku1> <sku2> <sku3>

D. Sync from directory

Bulk-manage IAP products from a directory of JSON files:

# Preview what would change
gpc iap sync --dir products/ --dry-run

# Apply changes
gpc iap sync --dir products/

Each JSON file in the directory represents one product. GPC compares local files against the Play Store and creates, updates, or deletes as needed.

Activating/deactivating OTP offers (v0.9.57+)

One-time product offers support explicit activation/deactivation:

gpc otp offers activate --app com.example.app --product-id sku_id --offer-id offer_id
gpc otp offers deactivate --app com.example.app --product-id sku_id --offer-id offer_id

Matches the subscription-offer lifecycle. Without this, OTP offers relied on state being set through batch update calls only.

5. Purchases — verification and lifecycle

A. Product purchases

# Verify a purchase
gpc purchases get <product-id> <token>

# Acknowledge (required within 3 days or purchase is refunded)
gpc purchases acknowledge <product-id> <token>
gpc purchases acknowledge <product-id> <token> --payload "order-123"

# Consume (for consumable products — allows re-purchase)
gpc purchases consume <product-id> <token>

B. Subscription purchases

# Acknowledge a subscription purchase (v1 — required within 3 days)
gpc purchases subscription acknowledge <subscription-id> <token>
gpc purchases subscription acknowledge <subscription-id> <token> --payload "order-456"

# Get subscription purchase details (v2 API)
gpc purchases subscription get <token>

# Cancel a subscription (v1 — requires subscription-id)
gpc purchases subscription cancel <subscription-id> <token>

# Cancel a subscription (v2 — supports cancellation types)
gpc purchases subscription cancel-v2 <token>
gpc purchases subscription cancel-v2 <token> --type DEVELOPER_CANCELED

# Defer expiry to a later date (v1)
gpc purchases subscription defer <subscription-id> <token> --expiry 2025-06-01T00:00:00Z

# Defer expiry (v2 — supports add-on subscriptions)
gpc purchases subscription defer-v2 <token> --until 2026-07-01T00:00:00Z

# Revoke a subscription (v2 API)
gpc purchases subscription revoke <token>

C. Product purchases (v2 API)

# Get product purchase details (v2 — supports multi-offer OTPs)
gpc purchases product get-v2 <token>

The v2 product purchase API returns ProductPurchaseV2 with line items, offer details, and multi-product bundle support.

D. Orders

# Get order details
gpc purchases orders get <order-id>

# Batch retrieve orders (up to 1000)
gpc purchases orders batch-get --ids "GPA.1234,GPA.5678"

E. Voided purchases and refunds

# List voided purchases (default: in-app only)
gpc purchases voided --start-time 2025-01-01 --end-time 2025-03-01

# Include subscription voids (type=1)
gpc purchases voided --type 1

# Include quantity-based partial refunds
gpc purchases voided --include-partial-refunds

# Refund an order
gpc purchases orders refund <order-id> --full-refund
gpc purchases orders refund <order-id> --prorated-refund

New in v0.9.47: --type 0 (default) returns only in-app purchase voids. --type 1 includes subscription voids. --include-partial-refunds includes quantity-based partial refunds.

All write operations support --dry-run.

Read: references/purchase-verification.md for server-side verification patterns and best practices.

6. Real-Time Developer Notifications (RTDN)

RTDN delivers Pub/Sub messages when subscription and purchase events occur. GPC can decode and inspect these notifications.

# Check RTDN topic configuration
gpc rtdn status

# Decode a base64-encoded Pub/Sub notification payload
gpc rtdn decode <base64-payload>

# Show setup instructions for RTDN
gpc rtdn test

Notification types include: SUBSCRIPTION_PURCHASED, SUBSCRIPTION_CANCELED, SUBSCRIPTION_RENEWED, SUBSCRIPTION_REVOKED, SUBSCRIPTION_EXPIRED, ONE_TIME_PRODUCT_PURCHASED, VOIDED_PURCHASE, and more.

New in v0.9.47: RTDN commands help debug subscription lifecycle events. Set up a Pub/Sub topic in GCP, configure it in Play Console > Monetization setup, and use gpc rtdn decode to inspect payloads.

7. Subscription analytics

Get insights on subscriber counts, conversion, and churn:

# Active subscribers, in-trial counts, trial→paid conversion, churn cohort
gpc subscriptions analytics

# JSON output for dashboards
gpc subscriptions analytics --json

Reports: active count, in-trial count, cancelled count, trial-to-paid conversion rate, estimated churn by cohort.

8. Base plan price migration

Migrate existing subscribers to a new price point:

# Migrate all subscribers on a base plan to a new price
gpc subscriptions base-plans migrate-prices <product-id> <base-plan-id> \
  --file prices.json

# Prices file format: regional prices JSON (same as base plan prices)

Subscribers are notified by Google Play and must accept or cancel. Use --dry-run to preview the migration.

9. Regional pricing

Convert a base price to all Google Play supported regions:

# Convert USD 4.99 to all regional prices
gpc pricing convert --from USD --amount 4.99

# Output as JSON for scripting
gpc pricing convert --from USD --amount 4.99 --json

The conversion uses Google Play's official exchange rates and rounds to locally appropriate price points.

Verification

• gpc subscriptions list returns your subscriptions
• gpc iap list returns your in-app products
• gpc purchases get <product-id> <token> returns v1 purchase details for a valid token
• gpc purchases product get-v2 <token> returns v2 purchase details with line items
• gpc purchases orders get <order-id> returns order details
• gpc pricing convert --from USD --amount 9.99 --json returns regional prices
• All --dry-run commands show what would change without modifying data
• JSON output works on all commands (--json flag)
