Use specific configurations

If you would like all of the agreements in your account that were sent outside of Adobe Sign to be created and pushed into Salesforce, follow these instructions:

• Copy the secure URL address from the Adobe Sign Callback Site you created and append /echosign_dev1__EchoSignAgreementPushCallback to compose the callback URL. Contact Adobe Support and provide them with your callback URL to set as your Adobe Sign account’s default callback URL. For example: If your site address is: https://echov11-dev.na12.force.com/AdobeSignCallback the callback URL will be: https://echov11-dev.na12.force.com/AdobeSignCallback/echosign_dev1__EchoSignAgreementPushCallback
• Adobe Support should also enter your Adobe Sign userID for the default callback URL API user setting. All accounts using Salesforce should also have their accounts set to append the document key to the callback URL.

If you are sending agreements via the API, follow these instructions:

• Copy the secure URL address from the Adobe Sign Callback Site you created and append /echosign_dev1__EchoSignAgreementPushCallback to create the callback URL to be used in the Adobe Sign API.
  • For example: If your site address is: https://echov11-dev.na12.force.com/AdobeSignCallback
    the URL you should use in the Adobe Sign API will be: https://echov11-dev.na12.force.com/AdobeSignCallback/echosign_dev1__EchoSignAgreementPushCallback
• When sending an agreement or creating a web form through the API you will need to provide a callback URL (see https://secure.echosign.com/redirect/latestApiMethods and reference the API parameter ‘CallbackInfo’.)
• Also make sure that your account settings are set to append the document key to the callback URL that should be the default for Salesforce customers using Adobe Sign. For any issues, contact Adobe Sign support.
• Additionally, go to Push Mappings Settings to define preferences for how records are created when agreements are pushed to Salesforce.
