**AWS Lambda** manages and invokes AWS Lambda functions using AWS SDK version 2.x.

## **Parameters**

Take a look at the configuration parameters for the connector. Parameters supported by [Double Braces expressions](https://docs.digibee.com/documentation/connectors-and-triggers/double-braces/overview) are marked with `(DB)`.

### **General tab**

<table data-full-width="true"><thead><tr><th>Parameter</th><th>Description</th><th>Default value</th><th>Data type</th></tr></thead><tbody><tr><td><strong>Dynamic Account</strong></td><td>When active, the connector will use the account dynamically. Otherwise, it will use the account statically.</td><td>False</td><td>Boolean</td></tr><tr><td><strong>Account Name</strong> <code>(DB)</code></td><td>The name of the dynamic account used by the connector. This account must have been previously configured in a <a href="../tools/store-account"><strong>Store Account</strong></a> connector in the pipeline for this process to take effect. It is only available if the <strong>Dynamic Account</strong> parameter is active.</td><td>N/A</td><td>String</td></tr><tr><td><strong>Account</strong></td><td>The account used by the connector. It is only available if the <strong>Dynamic Account</strong> parameter is inactive.</td><td>N/A</td><td>Account</td></tr><tr><td><strong>Function</strong> <code>(DB)</code></td><td>Name of the Lambda function.</td><td>N/A</td><td>String</td></tr><tr><td><strong>Fail On Error</strong></td><td>If the option is activated, the pipeline's execution with an error will be interrupted. Otherwise, the pipeline execution proceeds, but the result will show a false value for the <code>"success"</code> property.</td><td>False</td><td>Boolean</td></tr></tbody></table>

### **Optional tab**

<table data-full-width="true"><thead><tr><th>Parameter</th><th>Description</th><th>Default value</th><th>Data type</th></tr></thead><tbody><tr><td><strong>Override Endpoint</strong></td><td>Set the need for overidding the endpoint.

When using this parameter, the configuration will expect the lowercase name of the region (for example ap-east-1) You’ll need to use the name Region.EU_WEST_1.id()</td><td>N/A</td><td>String</td></tr><tr><td><strong>Trust All Certificates</strong></td><td>Whether to trust all certificates in case of overriding the endpoint.</td><td>False</td><td>Boolean</td></tr><tr><td><strong>Uri Endpoint Override</strong> <code>(DB)</code></td><td>Set the overriding URI endpoint.
