pending grant and waits for you to supply the key value from your own system, a third-party vendor, or a finite pool of codes.
By the end you will have:
- A product with a License Key entitlement set to
manualfulfillment. - A webhook listener that detects when a customer is waiting for a key.
- A fulfillment call that delivers the key and notifies the customer automatically.

API reference for the endpoint you call to deliver a key.
How It Works
Manual fulfillment changes only the issuance step. Activation, validation, deactivation, expiry, and revocation behave exactly like an auto-generated key once delivered.Prerequisites
To follow this guide you’ll need:- A Dodo Payments merchant account.
- Your API key (
DODO_PAYMENTS_API_KEY) and webhook secret key from the dashboard. See the API key generation guide. - A backend endpoint that can receive webhooks.
Use
https://test.dodopayments.com and test-mode credentials while building. Switch to https://live.dodopayments.com and live keys when you go to production.Step 1 — Create a License Key Entitlement in Manual Mode
An entitlement is a reusable definition of what you deliver. Create a License Key entitlement and set itsfulfillment_mode to manual.
- Dashboard
- API
Choose License Key
Select License Key as the integration and give it a Name. The form exposes these fields:
- Fulfillment Mode —
Automaticby default. This is the setting that enables manual fulfillment; you change it in the next step. - License Length — how long each issued key stays valid, or No expiration.
- Activations Limit — maximum activations per key, or Unlimited.
- Activation Message — optional customer-facing message shown when they activate the key.

Set Fulfillment Mode to Manual
Open the Fulfillment Mode dropdown and change it from Automatic to Manual. This is the setting that drives this entire guide — without it, keys are generated and emailed automatically and no pending grant is created. With Manual selected, each purchase creates a
pending grant for you to fulfill. Click Create Entitlement to save.fulfillment_mode defaults to auto. Omitting it, or leaving an existing entitlement unchanged, keeps the automatic behavior. Only entitlements explicitly set to manual create pending grants.Step 2 — Attach the Entitlement to a Product
Open the product you want to sell, expand Advanced Settings → Entitlements & Credits, and select the License Key entitlement you set to Manual in Step 1. A single product can deliver this license key alongside other entitlements on the same purchase.
Fulfillment mode is a property of the entitlement, not the product. Because you set it to Manual in Step 1, every product this entitlement is attached to creates
pending license-key grants on purchase — there is nothing extra to configure here.Step 3 — Detect Pending Grants
When a customer buys the product, Dodo Payments creates a grant inpending status with no key attached and fires an entitlement_grant.created webhook. This is your signal that a customer is waiting for a key.
Listen for the webhook
Set up a webhook endpoint (Developer → Webhooks in the dashboard) and act on pending license-key grants. The implementation follows the Standard Webhooks specification.integration_type: "license_key", so you can recognize a license-key grant without an extra lookup. See the Entitlement Grant webhook reference for the full payload.
Or poll the List Grants API
If you’d rather not rely on webhooks, list grants for the entitlement and filter byintegration_type and status:
Step 4 — Deliver the Key
Obtain the key value from your own system, then submit it with the Fulfill License Key Grant endpoint. This requires your secret API key (Editor permission); it is not one of the public license endpoints.Request fields
The license key string to deliver to the customer. Whitespace is trimmed; an empty or whitespace-only value is rejected.
Per-key activation limit. Falls back to the entitlement config when omitted.
Per-key expiry (ISO 8601). Falls back to the entitlement config’s duration when omitted. For subscription-issued grants, validity remains tied to the subscription regardless.
delivered, the customer is sent the key automatically (the same email they’d receive under auto fulfillment), and entitlement_grant.delivered fires.
The customer receives an email with the license key, the product, activation limit, expiry, and your activation instructions:

You do not need to email the key yourself — delivery happens automatically when the grant is fulfilled.
Step 5 — Handle Errors and Retries
The endpoint validates the grant before delivering anything. Handle these responses:| Status | Meaning | What to do |
|---|---|---|
200 | Key delivered, grant is now delivered. | Done. |
400 | Not a license-key grant, or the key is empty/whitespace. | Fix the request; do not retry as-is. |
404 | No grant with that ID for your business. | Verify the grant_id. |
409 | Grant not awaiting fulfillment (already delivered or already has a key), or the key value already exists. | If already delivered, treat as success. If a duplicate key, supply a different key. |
422 | Request body failed validation (e.g. activations_limit < 1). | Correct the field and retry. |
Verify the Flow
- Buy the product in test mode (see the checkout guides).
- Confirm your webhook received
entitlement_grant.createdwithstatus: "pending"andintegration_type: "license_key", or that the grant appears in the List Grants response with those filters. - Call the fulfill endpoint with a test key.
- Confirm the response shows
status: "delivered"with a populatedlicense_key, the customer receives the key email, andentitlement_grant.deliveredfires.
Once delivered, the customer can activate and validate the key against the public license endpoints exactly like an auto-generated key.
