# Missing TA1 acknowledgements for my transmissions

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

Anypoint Partner Manager sends TA1 acknowledgments for a received transmission if configured to do
so. Your partner might contact you to tell you that they are not receiving TA1 acknowledgments.

## Causes

Any of the following can lead to this type of error:

- The X12 settings for your partners are not configured to send TA1’s back to the partner.

- The endpoint to which you are sending that TA1’s back may be incorrectly configured.

## Solution

If you are not receiving TA1 configurations, review the following configuration:

1.  From within your Anypoint Partner Manager environment (either Sandbox or Production), select
    **Partners** and **Receive from <Partner\_Name>**.

2.  Scroll to Validation and Acknowledgment settings and click **X12**.

3.  Within the Acknowledgments section, ensure that the option for _Send TA1 for each transmission
    from <partner name>_ is selected.

4.  Configure the acknowledgment endpoint as in [Endpoints](https://docs.mulesoft.com/partner-manager/latest/endpoints).

5.  Click **Save** when done.

This enables TA1 acknowledgments for all transmissions received by the specific partner.
