Unable to access attachments from AGOL hosted feature layer

GIS_Admin — Thu, 11 May 2023 16:44:33 GMT

I am trying to author a flow where when a record is added to an AGOL hosted feature layer, I pull the attribute information and the attachment (photo) and email them to someone. Right now I use the When a record is created in a feature layer trigger then use the Fetch updates, changes, or deletions from feature layer action. This grabs all the attribute information, but will not return any attachments. The response shows an empty array:

When I use the REST endpoint of the service, I can see the attachment:

I tried using the Get attachment action and it's greyed out since there's no data getting passed:

Lastly, I tried the Get data from feature layer action and still get nothing for attachments.

Am I missing something here?

We use Make (formerly Integromat), and I'm not sure how different it is from Power Automate, but we just have our flow make a HTTP request to get attachments. Are you able to do something like that?

Quick response Josh! I can do the HTTP get to get the data, but was trying not to build it. I was hoping that the Get attachments action would get attachments.

I'm having the same issue, the fetch action is grabbing all of the expected attribute values but the attachments are empty. I had the same issue using the get attachment from URL

Good Day All,

When it comes to the webhook handling, there is a bit of a difference in application than what I think the group is expecting. When using the 'When a record is created' webhook, it is only returning the details about the feature service where the record was created. It is unaware of the other derivative components that might have been created in the record creation workflow.

If you are looking to get the attachments in a flow that is triggered by the feature service webhook, you can use the 'Get attachment' action and pass the record's ObjectID.

Hi Sean,

Are there any tutorials on how to include Get Attachment into a "When A Record Is Created" email flow? Every time I try to add this action it creates another "for each" loop and doesn't work.

Thanks!

Thank you for raising this get attachment action.

What about the attachment parameter which is mandatory?

Best,

Oussama

I have the same issue with the attachment parameter, can't get it to work properly.

Wondering if there is any further information on this @SeanKMcGinnis. Article/blog. What is the attachment parameter?

Hi all,

I figured out what the "Attachment" should be.

I hard-coded the Object ID (14) in this step.

Then, the attachment field will automatically give me the files associated with this item.

This is good, but if I were to use a variable in the Object ID field (such as within a loop), then, the Attachment field cannot find the files associated with the Object ID. Thus, this "get attachment" is not that useful at all.

Good find. So close, then denied. So seems like this doesn't work. Hoping this can get fixed, ESRI, or more specific documentation.

We ran into this same issue and were never able to figure out how to query attachments from either an ArcGIS when a feature updated or created trigger. Hopefully Esri considers this for an enhancement to work similar to the Survey123 triggers which make it easy to get attachments in Power Automate.

Our workaround was inspired by @jcarlson's post in this thread to use an http call to AGOL REST service to get the list of attachments for the record, then get the attachments themselves. This was fairly easy to implement:

@ArthurSmith2 are you using ArcGIS Enterprise or online?

In Enterprise you can try something like this:

In Online you can try something like this:

That said we do have this enhancement on our backlog and we will look into this.

ArthurSmith2 — Thu, 18 Dec 2025 00:16:09 GMT

Hey @AkshayHarshe thanks for the input! We are using ArcGIS Online.

We will try using the Query Attachments action... we missed this and were trying to use the Get Attachment action. That simplifies things a ton. Appreciate it!

Re: Unable to access attachments from AGOL hosted feature layer

AkshayHarshe — Thu, 18 Dec 2025 18:56:23 GMT

Yeah, In online we do have an enhancement to return the attachments form Extract changes endpoint. It is possible at the Enterprise connector at the moment.

Let me know if that works.

ArthurSmith2 — Mon, 22 Dec 2025 15:11:50 GMT

Great, that will be a useful enhancement!

We are now using your suggested workaround, and it works well. Look forward to simplifying even more when the enhancement is implemented. Thanks for your response!

That is great to hear that you were able to make it work.
