# Step 3: Design and Develop

Use the following resources to guide your work in this step:

* **Design Guidelines**
  * [Design Guidelines for the Platform-Managed flow](designGuidelinesPlatformManaged)
  * [Design Guidelines for the Merchant-Managed flow](designGuidelinesPartnerManaged)
* **Test Case Templates**
  * [Test Case Template for the Platform-Managed flow](../images/PlatformManagedTestCases_Partner.xlsx)

Using these materials, you can begin drafting your solution design document and test cases tailored to your selected [product lifecycle](subscriptionFlows).

Your Partner Ecosystem Management representative will also host a session to guide you through the process of creating your solution design and test cases. If your team needs additional support or clarification, we can schedule a technical deep dive session to assist further.

## Next Steps

Once your solution design and test cases are complete and submitted, your development team can begin implementing the integration based on your chosen [product lifecycle](subscriptionFlows) and the corresponding API specifications. Our team will continue to provide support as needed throughout the process.
