Enabling an API from a dataset

From the overview of a compatible dataset, you can easily enable an API giving access to the data it contains.

Before you begin

  • If you are using a Remote Engine Gen2, you have started the engine with the following command, to use a compatible engine profile: sudo ./remote-engine.sh start -r <region> -k <pair key> -p data-apis, where the value for your region can be us, eu, ap, or au.
  • The Dataset Administrator or Dataset Manager role has been assigned to you in Talend Management Console, or at least the View API and Manage API permissions.

Procedure

  1. From the dataset list, select the dataset you want to make available via API.
  2. To start configuring your API, from the overview of your dataset, you can:
    • Click the API tab of the left menu.
      Location of the API button.
    • Click Enable in the API tile.
      Overview of the API tile.
  3. Click Get started to reach the API configuration form.
  4. Enter an Entity set name, that constitutes the final API URL.
  5. From the Primary key drop-down list, select which field will be used to select specific records from the source dataset.
    The first field of the dataset is selected by default.
  6. Click Add to start defining the consumers that will be allowed to call the API.
  7. Enter the Name of the consumer.
  8. Choose your Authentication method in the Type drop-down list.
    • For Basic authentication, define the credentials that the consumer will use in the Username and Password fields.
    • For Api key authentication, click Generate API key and copy the resulting token to use in your request header.
  9. Click Add.
    The consumer is now visible in the list, and you can add more if you want.
    New consumer in the API.
  10. To finalize the API configuration and start the automatically generated API, click Enable.

Results

You are back in the API view of the dataset, this time with two tiles:
  • The Consuming tile, with the URL of the API to share with the consumers depending on if you are using http or https, examples of requests with more expressivity that you can easily reuse, as well as a download button to retrieve an OAS3 definition of your API. You can also use the Open in API Tester button to test a preconfigured API call in Talend API Tester.
  • The Monitoring tile, where you can monitor the activity of your API in the last 24 hours, and if the calls were successful or not.
Overview of the API tile.

You can use the Enable API switch to quickly disable or enable the API according to the situation, or click Edit to go back to the configuration form.

An overview of the API status and activity can also be found in the API tile of the dataset overview.

Information noteImportant: A known issue may prevent you from enabling an API from a dataset shared with you if:
  • the dataset is shared with user groups. In this case, try to share the dataset with other users individually.
  • the person who last modified the dataset or corresponding connection has lost their rights on the dataset. In this case, try to share it again with them, or contact your Talend support representative so that they update the dataset.
