Hello @LeoFPB,

Thank you for reaching out to the Docusign Community.

Currently, Docusign does not own any integrations with Flexmls or Form Simplicity, so we do not have the necessary documentation to assist you with this, you will need to contact them to get more information on any potential integration.

Note: Some advanced features and options are supported only in specific Docusign plans. Your account plan might not support some of the options discussed in this help topic. Contact your account administrator for more information about which options are available for your account. Or, visit our Plans and Pricing web page for more details on the features included with your plan. Compare eSignature plans & pricing.

Let us know if you need further assistance.

Best regards,
