Webhook FAQ

Do merchants have to build their own webhooks receptor?


What format does webhooks use?


Are webhooks sent in real time?

Yes, they are asynchronous; they will be sent as soon as each validation step is completed, regardless of the Flow Endpoint-Widget order.

Can webhooks be sent to an endpoint URL with a specific port?

No, the Webhook uses the default HTTPS port, 443.

What would happen if my webhook endpoint is unavailable?

We will retry to deliver the webhook after:

  • 1 minute
  • 3 minutes
  • 5 minutes
  • 7 minutes
  • 10 minutes

Webhooks are lost if delivery is unsuccessful. They can only be sent back if the validation is changed or updated on the dashboard.

You can also retrieve the webhook data using our API, under Retrieve Webhook Resource Data and Get Verification Media

What HTTP Request Methods can be used to obtain data from MetaMap through API?

Only GET and POST

What type of encoding is used on Timestamps?

Base 64.

For more information, go to our document on timestamps.

Is there is a limit on API requests?

For security purposes, merchants can only run three new verification requests per second. Users wishing to send batch data will have to set up their calls as such.
