WhatsApp Errors

YCloud failed to send messages

`whatsappApiError` in response body

You may get an error response body including the field error.whatsappApiError when you send WhatsApp messages by the YCloud API, typically the Send a WhatsApp message directly API.

Here is a sample error response with HTTP status 429 when you send too many messages to the same phone number:

{
  "error": {
    "status": 429,
    "code": "TOO_MANY_REQUESTS",
    "message": "(#131056) (Business Account, Consumer Account) pair rate limit hit",
    "target": "whatsappApiError",
    "docUrl": "https://developers.facebook.com/docs/whatsapp/cloud-api/support/error-codes",
    "requestId": "req_1KjtKI80IKoaJNa6n6p",
    "whatsappApiError": {
      "message": "(#131056) (Business Account, Consumer Account) pair rate limit hit",
      "type": "OAuthException",
      "code": "131056",
      "fbtrace_id": "A4O5a8RAgePwbcGSu",
      "error_data": {
        "messaging_product": "whatsapp",
        "details": "Message failed to send because there were too many messages sent from this phone number to the same phone number in a short period of time."
      }
    }
  }
}

In this case, we tried to request the WhatsApp Business API and got an error response. error.whatsappApiError is included to help you identify the error reason.

`whatsappApiError` in webhook payload

If you are using the Enqueue a WhatsApp message API, you will never get an error response having error.whatsappApiError since we submit your messages to the WhatsApp Business API asynchronously. You can get it by configuring a webhook listening for whatsapp.message.updated events. Here is an example of the webhook payload:

{
  "id": "evt_eEVCy8eNqD9EvcFI",
  "type": "whatsapp.message.updated",
  "apiVersion": "v2",
  "createTime": "2023-02-22T12:00:00.000Z",
  "whatsappMessage": {
    "id": "63f5d602367ea403f8175a6c",
    "wamid": "wamid.BgNODYxN...",
    "status": "failed",
    "errorCode": "131056",
    "errorMessage": "(#131056) (Business Account, Consumer Account) pair rate limit hit",
    "whatsappApiError": {
      "message": "(#131056) (Business Account, Consumer Account) pair rate limit hit",
      "type": "OAuthException",
      "code": "131056",
      "fbtrace_id": "A4O5a8RAgePwbcGSu",
      "error_data": {
        "messaging_product": "whatsapp",
        "details": "Message failed to send because there were too many messages sent from this phone number to the same phone number in a short period of time."
      }
    },
    "totalPrice": 0.0,
    "currency": "USD",
    "bizType": "whatsapp"
  }

Error Codes returned by the YCloud API

Be aware that error.whatsappApiError is not included when errors were detected by YCloud and we didn't request the WhatsApp Business API. For example, you provide an invalid phone number and then get the error response:

{
  "error": {
    "status": 400,
    "code": "PARAM_INVALID",
    "message": "Invalid E.146 phone number: +001",
    "target": "to",
    "docUrl": "https://docs.ycloud.com/v2/reference/errors#param_invalid",
    "requestId": "req_69UpMOaMHFrBMGZexYvUDw"
  }
}

The error.code is one of the YCloud server-defined error codes.

Listed below are some possible error codes returned by the YCloud API:

Code	Description	HTTP Status
PARAM_INVALID	One or more of the parameters is invalid.	`400` Bad Request
PARAM_MISSING	One or more of the parameters is missing.	`400` Bad Request
BALANCE_INSUFFICIENT	The account balance is insufficient.	`403` Forbidden
WHATSAPP_BUSINESS_ACCOUNT_UNAVAILABLE	The WhatsApp business account is unavailable.	`403` Forbidden
WHATSAPP_PHONE_NUMBER_UNAVAILABLE	The WhatsApp business phone number is unavailable.	`403` Forbidden
WHATSAPP_TEMPLATE_UNAVAILABLE	The WhatsApp template is unavailable.	`403`Forbidden
UNAUTHORIZED	Unauthorized. Make sure you are using the correct API Key in the 'X-API-Key' header.	`403` Forbidden

YCloud Error Codes conveyed by webhooks

If you are using the Enqueue a WhatsApp message endpoint, the message may fail due to a YCloud error. That is, the whatsappMessage.errorCode in webhook payload can also convey one of the YCloud Error Codes, such as BALANCE_INSUFFICIENT.

Here are some possible errors:

Error Code	Description	Possible Solutions
`INTERNAL_SERVER_ERROR`	Temporary due to downtime or due to being overloaded.	Wait and retry the operation. This error may be caused by a timeout in our call to the WhatsApp Business API.
`BALANCE_INSUFFICIENT`	Your account balance is insufficient.	Top-up.
`RECIPIENT_UNSUBSCRIBED`	The recipient has unsubscribed.	If you must deliver the message to the recipient, set the request parameter `filterUnsubscribed` to `false`, or go to Dashboard → Contact → Unsubscribe and remove them from the unsubscribe list.

Meta failed to send messages

Not all of the error codes listed in the WhatsApp Business Cloud API Error page are returned through the YCloud API. Even if a message is successfully submitted to the WhatsApp Business API, it may also fail to send. Meta notifies YCloud about these errors via webhooks. You should Configure Webhooks listening for whatsapp.message.updated events to receive these notifications from YCloud. Here is an example of the webhook payload for submitted but finally failed messages:

{
  "id": "evt_eEVCy8eNqD9EvcFI",
  "type": "whatsapp.message.updated",
  "apiVersion": "v2",
  "createTime": "2023-02-22T12:00:00.000Z",
  "whatsappMessage": {
    "id": "63f5d602367ea403f8175a6c",
    "wamid": "wamid.BgNODYxN...",
    "status": "failed",
    "errorCode": "131048",
    "errorMessage": "Message failed to send because there are restrictions on how many messages can be sent from this phone number.This may be because too many previous messages were blocked or flagged as spam.",
    "totalPrice": 0.0,
    "currency": "USD",
    "bizType": "whatsapp"
  }
}

The whatsappMessage.errorCode conveys the WhatsApp Business API Error code.

Meta Error Codes conveyed by webhooks

Listed below are some possible error codes conveyed by YCloud webhooks, that originated from Meta webhooks:

Code	Description	Possible Solutions
`131000` Something went wrong	Message failed to send due to an unknown error.	Try again. If the error persists, contact us to open a Direct Support ticket.
`131026` Message Undeliverable	Unable to deliver message. Reasons can include: • The recipient phone number is not a WhatsApp phone number. • Recipient has not accepted our new Terms of Service and Privacy Policy. • Recipient using an old WhatsApp version; must use the following WhatsApp version or greater: • Android: 2.21.15.15 • SMBA: 2.21.15.15 • iOS: 2.21.170.4 • SMBI: 2.21.170.4 • KaiOS: 2.2130.10 • Web: 2.2132.6	Using a non-WhatsApp communication method, ask the WhatsApp user to: • Confirm that they can actually send a message to your WhatsApp business phone number. • Confirm that they have accepted our latest Terms of Service (Settings > Help, or Settings > Application information will prompt them to accept the latest terms/policies if they haven't done so already) • Update to the latest version of the WhatsApp client.
`131031` Account has been locked	The WhatsApp Business Account associated with the app has been restricted or disabled for violating a platform policy, or we were unable to verify data included in the request against data set on the WhatsApp Business Account (e.g, the two-step pin included in the request is incorrect).	See the Policy Enforcement document to learn about policy violations and how to resolve them.
`131047` Re-engagement message	More than 24 hours have passed since the recipient last replied to the sender number.	Send the recipient a business-initiated message using a message template instead.
`131048` Spam rate limit hit	Message failed to send because there are restrictions on how many messages can be sent from this phone number. This may be because too many previous messages were blocked or flagged as spam.	Check your quality status in the WhatsApp Manager and see the Quality-Based Rate Limits documentation for more information.
`131049`	This message was not delivered to maintain healthy ecosystem engagement.	Do not retry immediately if you do receive this error code and suspect it is due to the limit. Instead, retry in increasing larger time increments until the message is delivered, since the limit may be in effect for differing periods of time. See Per-User Marketing Template Message Limits for additional information.
`131053` Media upload error	Unable to upload the media used in the message.	We were unable to upload the media for one or more reasons, such as an unsupported media type.
