custom field cascading populated trough API

[Henk Smets]

I would like to add a field to the create issue page to add the customer.

Because we have a lot of customers (500+), I would like the field cascading or searchable/autocomplete/... 

I should get its options via an external api.

Is this possible in the cloud version through a custom field with python, javascript or through a add on? I found this add on which exactly does what I'm looking for but it only exists the server-version (and not jira cloud). And I rather do it through an custom field to keep the number of add-ons under control. https://valiantys.atlassian.net/wiki/spaces/NFEED512X/pages/99942650/Configure+dependent+select+lists

thx a lot

Hi,

there is a Jira cloud App called "External Data for Jira Fields" that allows you to synchronise external data with a single or a cascading custom field. 

You can connect it with any external API that responds with JSON or XML. From then on the options will stay in sync (new values added & missing values disabled) so it always reflects your endpoint.

Hope this helps you solve your use case.
