Verify API

The verification API enables you to verify whether a user currently has access to a given phone number or email address by sending them an OTP and requesting that they verify the code sent to them.

This can be achieved by using the following API endpoints below.

Currently, Verify supports Email, WhatsApp, and SMS channels

Sending a Verification

In order to send a message, you must have an active channel and perform an HTTP request to the following endpoint using a valid access key.

Creates a new verification message

post

Creates a new verification message

Authorizations

HTTPRequired

Uses the Authorization header: 'AccessKey ' followed by your access key token (e.g., 'Authorization: AccessKey AbCdEfGhIjKlMnOpQrStUvWxYzAbCdEfGhIj')

Path parameters

The ID of the workspace

Body

localestring · locale-bcp47Optional

The locale/language of the message sent to the user. If not provided, we will attempt to determine the locale from the user's phone number. If we are unable to determine the locale, we will default to "en-US".

Here is an example of a basic verify request body for SMS

{
  "identifier": {
    "phonenumber": "+31623456789"
  },
  "steps": [
    {
      "channelId": "SMS_CHANNEL_UUID"
    }
  ]
}

Steps

You can use Steps to implement a failover strategy between different channels. The minimum number of steps is one. Calling the failover endpoint will cause it to move to the next step.

{
  "identifier": {
    "phonenumber": "+31623456789",
    "emailaddress": "[email protected]"
  },
  "locale": "en-US",
  "maxAttempts": 3,
  "timeout": 300,
  "codeLength": 6,
  "steps": [
    {
      "channelId": "CHANNEL_UUID"
    },
    {
      "channelId": "FAILOVER_CHANNEL_UUID"
    }
  ]
}

Instead of using an SMS channel step, use an SMS navigator. Navigators offer two key advantages:

Improve Reliability: Your integration remains consistent, preventing any changes, additions, or deletions to your channels from impacting your verification requests.
Improved Coverage: The best available channel will be used based on the country of the number you are trying to verify, increasing your conversion rate.

You can achieve this by using the following syntax, based on the UUID you can find in Developers -> Navigators -> Navigator Setup -> OTP:

"steps": [
    {
        "navigatorId": "OTP_navigator_UUID"
    }
]

Templates

Verify supports using templates for some channels. The following is an example of using a channel with a template.

{
  "identifier": {
    "phonenumber": "+31623456789",
  },
  "steps": [
    {
      "channelId": "CHANNEL_UUID",
      "template": {
        "projectId": "TEMPLATE_UUID",
        "version": "TEMPLATE_VERSION_UUID|latest",
        "locale": "en"
      }
    }
  ]
}

SMS Templates

Sending SMS Verify messages can be done in two ways:

Using our pre-defined message body. You can change the language by setting the locale of the verification; the body language is derived from the given locale.
1. Supported languages include:
  1. Afrikaans (af)
  2. Arabic (ar)
  3. German (de)
  4. English (en)
  5. Spanish (es)
  6. French (fr)
  7. Italian (it)
  8. Dutch (nl)
  9. Polish (pl)
  10. Portuguese (pt)
  11. Russian (ru)
  12. Turkish (tr)
Using a customer-defined template. The template should contain a variable named otp which is used for the generated OTP Code.

Email Templates

For emails, templates work just as you would expect via the channels API, with the addition of a variable for the Verify OTP Code.

When setting up a template for Email, select {} -> Verify -> OTP from the list of variables

WhatsApp Templates

Templates for WhatsApp channels are required. To send an OTP message to a WhatsApp channel, you must have an Authentication Template set up.

Verifying the code

Once you have received a code from one of your users, you will have to confirm if the code is valid.

Failover to the next step

You can failover to another verification step by calling the following endpoint.

By not setting a value for stepIndex, it will default to the next step in the array.

Auto Failover

Verify will automatically failover to the next step when a step fails to send or deliver, provided the next step is on a different platform.

Examples:

Different Platforms:
- If two steps are used: the 1st is WhatsApp, and the 2nd is SMS, the SMS will automatically be sent if the WhatsApp message fails to send or deliver.
- If two steps are used: the 1st is SMS, and the 2nd is Email, the email will automatically be sent if the SMS fails to send or deliver.
Same Platform:
- If two steps are used, and both are SMS, the second SMS will not be automatically selected if the first SMS fails.
- This is because Bird assumes that if one type of SMS fails, all SMS will fail, as they rely on the same infrastructure.
