# WhatsApp Cloud API error 131026

This page documents WhatsApp Cloud API error `131026`.

Meta will deprecate error titles. Match on `code` and `details`, not on the title in `message`.

Official table: [WhatsApp Cloud API error codes](https://developers.facebook.com/docs/whatsapp/cloud-api/support/error-codes/).

## Match these fields

| Field                | Value                                                           |
| -------------------- | --------------------------------------------------------------- |
| `code`               | `131026`                                                        |
| `error_data.details` | Unable to deliver message. Reasons can include the cases below. |

Do not build handlers on titles such as `(#131026) …`. Those titles live inside `message` and will be deprecated.

## Official `details`

Unable to deliver message. Reasons can include:

* The recipient phone number is not a WhatsApp phone number.
* Recipient has not accepted the new Terms of Service and Privacy Policy.
* Recipient using an old WhatsApp version. The recipient must use this 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

## Official next step

Use a non-WhatsApp channel. Ask the WhatsApp user to:

* Confirm that they can send a message to your WhatsApp Business phone number.
* Confirm that they have accepted the latest Terms of Service. **Settings** > **Help**, or **Settings** > **Application information**, will prompt them if they have not accepted the latest terms.
* Update to the latest version of the WhatsApp client.

## Fields to read

Read `code` and `error_data.details`.

Ignore the title inside `message`.
