FAQ
Following are some common questions for this specific API:
Why do need to pass a transaction_id?
This value is useful to refer to a specific transaction in the system. Using only the phone number can lead to collision in case of duplicated call for the same phone number. Transaction id must be unique across all trustfull api endpoints.
What is the supported phone_number_format?
The phone_number parameter must be submitted in international format, using digits only. This means the number should include the country code directly followed by the national number, without any leading zeros, plus symbols, spaces, or special characters.
What happen if i pass an invalid phone_number?
We strongly encourage you to validate the phone number format before making a request, or to use our Phone Validation endpoint
If the phone_number provided has an invalid format, the response will only include the is_valid_format field (false)—charged at the same rate as a standard API call.
