Discover and consume catalog assets

Find a catalog asset
Start by searching the Amplify Unified Catalog to find the asset. By default, catalog assets are sorted by the most recently items published or updated first. Those assets are marked with New or Updated labels at the top of the list.
If you don’t know exactly what you are looking for, you can type a keyword in the search bar to search for assets. The result will return all catalog assets that have the search term either in the name or in the tags fields. You can further refine your search by using the Filter by Category and Type.
Watch the animation to learn how to search and filter in the Unified Catalog.
Subscribe to an API
The provider of the API asset can configure when a subscription is required, and the metadata to be provided for the subscription. In this case, before using the API, you must subscribe to request access to use it. The Subscribe button is not displayed if the API asset was configured not to require a subscription, or if the API is not protected with an API Key.
Follow these steps to subscribe to an API asset:
Select Catalog in the left navigation bar.
Select an API asset in the list to see a detailed view of its description, test methods, and subscriptions.
Click Subscribe in the top right corner.
On the dialog box, enter a name for the subscription.
(Optional) Enter a short description. This can be used to let the asset provider know how you intend to use the API.
Select an Application.
Amplify Central administrators can subscribe an application on behalf of API consumers. In this case, they will be required to select the Team that will own the subscription.
Watch the animation to learn how to subscribe to an API asset.
When subscription requests to an API are set to be manually approved by the API provider, a Request access button is shown. After you click to request access, a message is displayed to inform that the subscription request has been submitted and is awaiting for approval.
A successful subscription flow looks like this:
- When a subscription is created, the subscription state is set to Waiting for approval.
- The subscription stays in this state until the request is approved, either automatically or manually, by the asset provider.
- When the request is approved, the subscription state is set to Subscribing, and the access is provisioned.
- After the provisioning is complete, the subscription state is set to Active. Depending on how the subscription flow was configured by the provider, you can receive the API credentials or you can generate the credentials on the Application that was selected when subscribing.
When the provisioning fails, the subscription state is set to Subscribe Failed. For instance, the subscription could fail because the application was not given access to the API. You could try to re-subscribe by editing the subscription and providing a different application.
Subscribe to an MFT asset
By subscribing to an MFT service, you request access to exchange files with your partners.
Follow these steps to subscribe to an MFT asset that enables Account-to-Account (A2A) exchanges.
- Select Catalog in the left navigation bar.
- Select an MFT asset and click Subscribe from the top right corner.
- On the dialog boxM enter a name for the subscription.
- (Optional) Enter a short description. This can be used to let the asset provider know how you intend to use the API.
- Choose an Application for the target App.
- Select a Profile for the target App.
- Choose an Application for the source application.
- Select a Profile for the source application. For more information, see Create a CFT profile.
- Click Subscribe.
NoteAfter the subscription request has been submitted, a subscription entry is automatically created in Flow Manager and a flow will be deployed that enables the transfer files between the registered applications. For more information, see Flow Manager.
A subscription is created in Requested state. When its status changes to Active, the flow is deployed successfully.
The following is a list of all possible subscription states:
- Waiting for approval: The user has submitted a subscription request, and is awaiting approval by the asset provider.
- Subscribing: The subscription request was approved, and the flow is being deployed.
- Rejected: The subscription request was rejected by the asset provider.
- Active: The flow was successfully deployed.
- Subscribe Failed: There was an error during the deployment of the flow.
- Change Requested: A change request was submitted by the consumer. Change requests can be approved or rejected by asset providers.
- Unsubscribing: The user has requested to unsubscribe from the asset. The flow is being removed.
- Unsubscribed: The flow was successfully removed from Flow Manager.
- Unsubscribe Failed: There was an error with the removal of the flow in Flow Manager.
Edit a subscription
You can change the details of a subscription (for instance, when you want to select another application) from the Subscriptions page. To edit a subscription:
- Select Subscriptions in the left navigation bar.
- Click a subscription to view its details.
- Click Edit.
- After you enter the new values, click Update.
After you submit your changes, the subscription will transition to Change Requested. The subscription stays in this state until the change request is approved, either automatically or manually, by the asset provider.

Promote an API to Integration Builder
If you are leveraging the Amplify iPaaS to create integrations between different applications, you can promote an API from the Unified Catalog to Integration Builder as a custom connector with a click of a button. This saves you the trouble of exporting the swagger file and manually import it in Integration Builder. To lean more, see Amplify Integration Builder.
You can promote an API published in the Unified Catalog to Integration Builder as a custom connector. Before you start, ensure that you have access to Integration Builder, and that have your API secured, as well as a valid subscription. For details, see Subscribe to an API.
To promote an API as a connector template:
- Navigate to Unified Catalog.
- Select an API asset. From the details screen, click the More Options menu, and select Export from the dropdown list.
- Select either the Production or Sandbox Integration Builder environment where you want to use this API. This option is not shown when you have only one environment activated with your Amplify platform license.
- Enter a Connector Name for the template. This name is mandatory and it has the API asset name by default.
- (Optional) Enter a short description in the Connector description box.
- Click Export.
TipYou must have the Central admin role or the Developer team role assigned, and Integration Builder activated to view the Export option.
Now you can navigate to Integration Builder to use your connector.
Watch the animation to learn how to promote an API as a connector template.
