Host your own Embedded Signup

For even more personalization, if you are an approved Meta Tech Provider, you can also host your own Embedded Signup flow.

Requirements

Tech Provider registration and approved Solution

To enable this option, you must be a Meta approved Tech Provider and have a live Solution with 360dialog.

See more details in our documentation.

• Understanding the Meta Tech Provider Program

Meta Tech Provider Program

Technical capacity to host and manage your own Embedded Signup

You will also need to be able to host and manage your own Embedded Signup script, which requires technical knowledge. We will not be able to support you on troubleshooting your own Embedded Signup.

Request Advanced Access for public_profile permission

To host your own embedded signup, you must add extra permission for the process to work smoothly. In the Meta for Developers App dashboard > navigate to your App Review > Permissions > Find the ‘public_profile’ permission and request advanced access.

Ensure advanced access is granted before configuring the ES.

Cloud API enabled

As announced in November 2023, Meta is transitioning to a fully Cloud-hosted WhatsApp Business Platform and will stop supporting On-Premise API in October 2025. Starting from On-Premise client v2.53, all new feature updates will be exclusively delivered to Cloud API. While the On-Premise API client will receive quarterly releases, they will focus solely on bug fixes and security patches.

• See differences between On-premise API and Cloud API

• Enable Cloud API in your Partner Hub to be able to register Cloud API numbers

• Learn how to change hosting type of registered numbers

This option is only available if your Partner Hub is already enabled for Cloud API.

Set Partner Hub Webhook URL and listen to Webhook Events

Building the Integration

Step 1: Create or retrieve a Client Account

In order to later submit the number, you need to either retrieve an existing client_id or create a new client instance through our Partner API using the endpoint below. Make sure to store the Client ID of each client within your database, since it will be required afterwards. Alternatively, you can also retrieve it with this endpoint.

Create client account

POST https://hub.360dialog.io/api/v2/partners/{partner_id}/account_sharing/clients

Request example curl --request POST --url https://hub.360dialog.io/api/v2/partners/partner_id/account_sharing/clients --header 'Accept: application/json' --header 'Authorization: Bearer 123' --header 'Content-Type: application/json' --data '{ "name": "string", "email": "string", "user_name": "string"}'

Request Body

Name	Type	Description
name*	string	Name of the client user
email*	string	Email address of the client user.
user_name*	string	Name of the client user.

201: Created

  "id": "string", // ID of the Client

Step 2: Surface Embedded Signup to client and fetch information

When the Embedded Signup is completed by the client, you can use the code received in the payload to fetch detailed WABA information. See more here and here.

Step 3: Connect Client account to registered Phone Number

Use the endpoint below to submit the phone number/channel to 360dialog records. If the number was successfully onboarded via self-hosted Embedded Signup and the attached client_id matches the user data in 360dialog records, the onboarding flow end by redirecting the Client to the Partner Redirect URL set.
