# Get Embedded Signup SDK config

`GET /v1/connect/whatsapp/sdk-config`

The Meta app id and Embedded Signup configuration id the Zernio-hosted signup page uses to open Meta's
popup. Integrators do not need this endpoint: start the hosted flow with
`GET /v1/connect/whatsapp?signup=hosted` and send the user to the returned `authUrl`. Authenticates with
an API key or with the connect token the hosted flow issues (`X-Connect-Token` header).

## Headers

- `X-Connect-Token` string

## Response `200`
