Deleting a Data Source

Data sources can be deleted from your organisation. To delete a data source:

  • Navigate to the Data sources page.
  • Click on the delete icon for the data source you want to remove.

Delete a data source

Clicking on the delete icon will open a confirmation dialog. Click the Confirm button to confirm the deletion or Cancel to close the dialog without deleting the data source.

Delete data source confirmation

Clicking Confirm will delete the data source, but it will not remove the data source from any stubs that are using it. These stubs will continue to reference the deleted data source, but will act as if no data was returned when the data source is queried. See below for more details on stub matching and response templating when a data source is deleted.

When a data source is deleted, any data source limits you may have reached will be re-evaluated. If you have any disabled data sources, they will be re-enabled if you now have available capacity within your data source limits. You can read more about plan limits and disabled data sources here.

Any stubs that are using the deleted data source will now have a warning message displayed on the stub informing you that The data source that this stub was referencing no longer exists. You will also see a warning icon next to the data source summary in the stub form.

Data source stub warning icon

If you have other data sources within your organisation you can attach one of these to the stub to replace the deleted data source. If you do not have another data source that you can use, you will need to update the stub to remove the reference to the deleted data source.

You can do this by clicking on the delete icon next to the data source in the stub form.

Stub Matching

If a stub is using a data source that has been deleted, the stub will no longer match incoming requests if the Matches stub only if data is found tick box is checked on the Stub form. If this tick box is not checked, the stub will continue to match incoming requests, but the data source will not be queried.

Data source response templating

If a data source is deleted, any response templates that are using the data source will no longer be able to access the data source data. The response template will still be rendered, but the data source data will not be available.
