Connecteurs Power automate ArcGIS pour couche d'entités AGOL (hébergée, vue)

LouiseG

Bonjour communauté ESRI, je cherche de la documentation ou des conseils sur la façon d'utiliser les connecteurs Power Automate ArcGIS pour les couches d'entités ArcGIS Online (hébergées, vue). <\/P>

Nous avons une couche d'entités hébergée modifiable, et nous utilisons Power Automate pour : <\/P>

1) Publier un message dans un chat de groupe nommé MS Teams lorsqu'une nouvelle entité est créée<\/P>

2) Publier un message dans un chat de groupe nommé MS Teams lorsqu'une entité est mise à jour<\/P>

À partir de la couche d'entités hébergée, nous avons six couches d'entités modifiables (hébergées, vue). Les modifications seront effectuées sur ces couches de vue plutôt que sur la couche d'entités hébergée principale. <\/P>

Nous avons créé les flux de travail Power Automate, mais ils ne se déclenchent que lorsque les connecteurs ArcGIS pointent vers les couches de vue, plutôt que vers la couche d'entités hébergée principale. D'après la lecture d'autres publications communautaires (par exemple ici<\/A> et ici<\/A>) il semble que les connecteurs Power Automate doivent pointer vers les couches de vue. <\/P>

Quelqu'un pourrait-il me confirmer si cela est correct ? Nous trouvons excessif de devoir activer « Keep track of changes to the data » sur chaque couche de vue, et potentiellement créer 12 flux Power Automate. <\/P>

Merci beaucoup, <\/P>

Louise<\/P>

What is your trigger for the flow? Anything that isn't on a schedule (e.g., something that runs every x minutes) can result in delays. For example, any time I have a flow with "When an item is updated", it can either trigger instantly, or a minute later.

And to add on to that, email/email servers can also be slow. I've watch a multi-part approval flow finish to completion, and then 30 seconds later get several emails back-to-back for the different flow steps. Teams would be the same as this.

Personally, I hate the reactive triggers as they never seem to trigger when I expect them to. Also, I find the Survey123 reactive triggers (which I used a lot) very unreliable. Instead, I put everything on a schedule, and if nothing is found the flow is cancelled. I've never had a problem with this, and if an error is encountered, the flow can just reset and try again later.

I will add that if you go with the schedule approach, you need a dedicated field that can updated by the flow so once something is processed, it isn't reprocessed unintentionally.

I don't think any of my flows are pointing to View layers, so that sounds wrong to me. Using the main FL should work, since that is where all the data ends up.

Agreed to the comment above. It is requirement of webhooks to have changes tracking enabled and ArcGIS connectors have the same requirements for you to trigger the webhook. Webhooks in ArcGIS Online—ArcGIS Online Help | Documentation

Thank you @abureaux and @AkshayHarshe for getting back to me.I can confirm that changes tracking is enabled on the main hosted feature layer.

I turned off the Power Automate flows connecting to the view layers and did some testing today with the Power Automate flows connected to the main hosted feature layer. I created a point on a view layer but it didn't generate a MS Teams notification, then I waited a few minutes and tried it again but got no notification. Then a few minutes later I created a point on the main hosted layer, within two minutes I got two MS Team notifications at the same time for all three created points.

I have done some testing on the webhook using webhook.site. I do not receive a POST from the webhook when a feature is created on the View layer, but I do receive a POST when a new feature is created on the main feature layer. I have tested this with the webhooks created by Power Automate and with another webhook created in ArcGIS Online.

Triggers by nature are reactive, what @abureaux is a way you can bypass the triggers and check periodically to see if there are changes. It does add overhead but could be useful in certain scenarios.

How the webhooks are triggered is completely out of control of ArcGIS for Power Automate connectors. ArcGIS Online/Enterprise webhooks handle everything. Power automate is and our connectors will only know to run a flow when the Webhook says that it has new changes. The fetch action will get run extractChanges endpoint on Feature Server to retrieve changes that webhook collected. It is normal to have some delay running a webhook as someone making several edits to features layer(s) gets pooled to trigger once instead of making lot of requests.

Hi @abureaux and @AkshayHarshe

Thank you both for your advice on my query.

I was using the 'When a record is created in a feature layer' trigger, this works as expected when edits are made to the main hosted feature layer, but not when edits are made through one of the view layers. This seems to related to the webhook rather than the connector/trigger.

I have recreated the flow so it is now on a schedule and uses a control field as suggested here: https://community.esri.com/t5/arcgis-survey123-questions/generate-feature-report-in-power-automate-directly/td-p/1384495 (again, thank you @abureaux for this resource). The flow now posts a MS Teams message regardless of whether the edits were made on the hosted layer or the view layer.
