Create a SOAP URL in Postman

You must create a SOAP URL to post the request with the Base64 zip file for field mappings.

1. Open a new tab in Postman to create another POST request.
2. Select POST and paste this URL https://{ORG_URL}/services/Soap/m/55.0.
3. Replace the org variable in the URL with actual data:
   {ORG_URL}: Type the URL of your org.
4. Click Headers.
   The application lists the default headers.
5. Add additional headers:
   1. Key: Content-Type, Value: text/xml
   2. Key: SOAPAction, Value: deploy
6. Click Authorization.
7. Select Bearer Token as Type.
8. Paste the access token that you got from the previous step in the Token field.
9. Click Body and select raw.
10. Paste this code into the body:

    <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:met="http://soap.sforce.com/2006/04/metadata">
    <soapenv:Header>
    <met:SessionHeader>
    <met:sessionId>{ACCESS_TOKEN}</met:sessionId>
    </met:SessionHeader>
    </soapenv:Header>
    <soapenv:Body>
    <met:deploy>
    <met:ZipFile>{ZIP FILE TO BASE 64 CONVERSION STRING}
    </met:ZipFile>
    <met:DeployOptions>
    <met:allowMissingFiles>false</met:allowMissingFiles>
    <met:autoUpdatePackage>false</met:autoUpdatePackage>
    <met:checkOnly>false</met:checkOnly>
    <met:ignoreWarnings>false</met:ignoreWarnings>
    <met:performRetrieve>false</met:performRetrieve>
    <met:purgeOnDelete>false</met:purgeOnDelete>
    <met:rollbackOnError>false</met:rollbackOnError>
    </met:DeployOptions>
    </met:deploy>
    </soapenv:Body>
    </soapenv:Envelope>
    

11. Replace the {access_token} variable with the access code that you got in the previous step.
12. Replace the {ZIP FILE TO BASE 64 CONVERSION STRING} variable with the base64 version of the zip file that you created in the previous step.
