      summary: Allows a registered partner to create or update merchant participation details
      description: 'This endpoint enables registered partners to manage merchant participation details, indicating whether a merchant has opted into or out of Buy Now Pay Later. A unique MAID-based merchant is identified by a combination of acquirerICA, merchantLegalName, and countryCode. <br><br> It facilitates the creation of a merchant with participation and allows updates to existing participation information, such as adding more MIDs, toggling opt-in flags, modifying address fields, and updating wallet information. <br><br> Additionally, this API supports the submission of MAID-based merchant participation,Identification of existing MID based merchants relies on acquirerICA, merchantLegalName, and countryCode and MAID based merchants relies merchantLegalName, and countryCode <br><br> If a merchant already exists, the provided MIDs will be appended to the current set.Once a MAID is entered into the system, it becomes immutable. Certain fields, namely duns cannot be modified; they must either be null, empty, or match existing values, or a 400 bad request error will be thrown. This API also allows for updating MAID base participation submitted by other acquirers. <br><br> Various markets can utilize this API to submit MAID or MID participation. For further information, please contact the Product team. <br><br> Upon successful validation and acceptance of a request, the API returns the request ID in the ''request_id'' response header, and processing occurs asynchronously. Use the GET /merchants/participation endpoint to monitor request status via the request ID. When initiating participation requests, ensure that the total payload size remains under 700 KB to avoid errors. <br><br> The field `nonMerchantNegotiatedParticipation` will be deprecated. It is recommended to utilize the `optIn` flag instead. In cases where both fields are provided, the `optIn` field will take precedence over `nonMerchantNegotiatedParticipation`. <br><br> We have introduced a new field called `merchantGroup` which is optional for other market but mandatory for markets like Australia. <br><br> Please see the table below for market/operation wise field validation: <table> <tr> <td>Market</td> <td>Mandatory In Add Operation</td> <td>Mandatory In Update Operation</td> </tr> <tr> <td>MID Market</td> <td><b>merchantLegalName</b>, <b>countryCode</b>, <b>acquirerICA</b>, <b>dbaNames</b>, <b>mids</b>, <b>optIn(or nonMerchantNegotiatedParticipation for previously onboarded customers to API)</b>  </td> <td><b>merchantLegalName</b>, <b>countryCode</b>, <b>acquirerICA</b>, <b>optIn(or nonMerchantNegotiatedParticipation for previously onboarded customers to API)</b></td> </tr> <tr> <td>Australia MID Market</td> <td><b>merchantLegalName</b>, <b>merchantGroup</b>, <b>countryCode</b>, <b>acquirerICA</b>, <b>dbaNames</b>, <b>mids</b>, <b>optIn</b>  </td> <td><b>merchantLegalName</b>, <b>countryCode</b>, <b>acquirerICA</b>, <b>optIn</b></td> </tr> <tr> <td>MAID Market</td> <td><b>merchantLegalName</b>, <b>countryCode</b>, <b>acquirerICA</b>, <b>dbaNames</b>, <b>maid</b>, <b>maidType</b>, <b>optIn</b>  </td> <td><b>merchantLegalName</b>, <b>countryCode</b>, <b>acquirerICA</b>, <b>maid</b>, <b>maidType</b>, <b>optIn</b> </td> </tr> </table>
