Webhook notifications [Payouts API]

Monitor the status of payouts and top-ups using webhooks, and validate webhook signatures.

Payouts API will notify you of the following events using webhooks:

  • Payout authorised
  • Payout submitted
  • Payout settled
  • Payout rejected
  • Payout failed
  • Topup received

Details on the overall structure of webhooks, as well as their payload schemas, are below.

Webhook retry policy

We consider a webhook as having been successfully delivered when we receive a success status code (2xx) from the webhook URI you specified in your Console settings for Payouts API.

If we receive any other status code (for example, your API is temporarily unavailable), we will start retrying.

Our retry policy is jittered exponential backoff: we will immediately perform some fast retries and then start waiting increasingly longer; we will keep retrying for up to 72 hours.

Validate the received webhook signature

We recommend developers to use our signing libraries to verify the Tl-Signature of the received webhooks.

        .path(path)
