Identifying the Symptom: Invalid Sender ID

Exploring the Issue: What Causes Invalid Sender ID?

The 'Invalid Sender ID' error occurs when the sender ID used in your API requests is not registered or approved by Sinch. Sender IDs are unique identifiers that represent the sender of the message, and they must comply with regulatory requirements and be approved by Sinch to ensure message delivery.

Common Causes of Invalid Sender ID

  • Using a sender ID that has not been registered with Sinch.
  • Attempting to use a sender ID that has not been approved for your account.
  • Typographical errors in the sender ID specified in the API request.

Steps to Resolve the Invalid Sender ID Issue

To resolve the 'Invalid Sender ID' error, follow these actionable steps:

Step 1: Verify Sender ID Registration

Ensure that the sender ID you are using is registered with Sinch. You can check your registered sender IDs in the Sinch dashboard. If the sender ID is not listed, you will need to register it.

Step 2: Register the Sender ID

To register a new sender ID, log in to your Sinch Dashboard and navigate to the 'Sender IDs' section. Follow the prompts to submit a request for a new sender ID. Make sure to provide all necessary information and comply with any regulatory requirements.

Step 3: Await Approval

Once you have submitted your sender ID registration request, it will be reviewed by Sinch. Approval times can vary, so be sure to check the status of your request regularly. You will receive a notification once your sender ID is approved.

Step 4: Update Your API Requests

After your sender ID is approved, update your API requests to use the correct sender ID. Double-check for any typographical errors and ensure that the sender ID matches exactly as registered.
