get https://example.com/api/v1/paymentmethods//webhooks-trigger/transaction/
This endpoint can be used to trigger the webhooks for a transaction manually. Calling this endpoint might
cause the webhook to be send multiple times (by the automated system and the manual trigger).
Contrary to the normal flow of a webhook where it is scheduled only when there is an update in the status of
the transaction, this endpoint DOES NOT have any validation on the status of the transaction, meaning that users
can use this endpoint to trigger the webhooks of a transaction any time.
