Issue with Order Push to Shopify using Custom App

[eleganceindia]

When attempting to push orders  to Shopify using the Custom App, we are encountering an error message indicating a failure in the order transfer process by using WhatsApp Commerce using API. Earlier it was working fine, and after 1 week it's stop working.

{
  "error": {
    "message": "Unauthorized",
    "metadata": {
      "data": {
        "errors": "[API] Invalid API key or access token (unrecognized login or wrong password)"
      },
      "addData": null
    },
    "name": "BadRequestError"
  }
}

It could be a few things. Your API key/access token may have expired or been revoked. Check WhatsApp Commerce to see if that's the case. You might need to adjust the permissions in your Shopify admin settings. After you've tried all that, try regenerating the tokens and testing in a dev store.
