Where is submission_url stored when HFS is created along with survey?

TL2 — Mon, 21 Jul 2025 21:57:54 GMT

When you create a survey it generates the hosted feature service and links them. When you add a field the linked HFS is updated.

I would like to point my survey to a different HFS but would like to avoid adding a submission_url. I would like to update the linked HFS.

My submission_url is blank so somewhere the survey knows which HFS to use, but I can't find it.

Thanks.

There's no recommended way to do this.

You would need to modify the form info files in survey123 connect.

E g. formInfo.json and change the "featureServiceItemId" to your new HFS's item ID.

This should update the item data property in the published form in ArcGIS online.

However, I strongly recommend you don't go down this path because:

It's not a supported workflow
It's common to encounter issues when manually modifying the local files or moving/renaming survey content in ArcGIS Online
It's more effort than the alternate supported workflows

Instant I would recommend:

Use the submission_url and manually add fields as required to the layer and form
Publish a new survey form to create a new associated layer, and then migrate your data from the original layer.
