Hi everyone, I have a product that runs on Dotnet Core and has, right now, in-built features that prospects have to confirm first if they want to use it. Currently, if they click on it, they will be confronted with a pop-up and a notification will be send to our Sales team. However, I read that I can integrate an API in our product so that when a prospect selects a feature that they want to use that they automatically come in a workflow and could receive a mail and/or more information. This way I can keep our Sales inbox clean, but I’m struggling to figure out which API is the best for this. Can someone help me on this? Thanks! ---

Hey @RLV2525 Welcome to the Community! My initial thought on this would be to update a contact property with the [CRM Objects endpoint](https://developers.hubspot.com/docs/api/crm/contacts) which would trigger a workflow and start your automation. The [workflow](https://knowledge.hubspot.com/workflows/get-started-with-workflows) portion could be handled in UI. @Kevin-C , @Bryantworks what do you think? ---

Hey @RLV2525, I’ll echo @dennisedson suggestion here. I use the CRM Objects endpoint to force trigger workflows all the time, it’s very reliable for this. You do end up creating several “flags” though. ---

Hi Chris & Dennis, Thanks for your quick replies! I will try to use the CRM Objects and see how it works. However, what do you mean by “flags”? Thanks! ---

Hey @RLV2525, by flags I’m meaning custom properties. You might need to create properties when a user takes action to “flag” that user in HubSpot with a property moving from “true” from “false” for example.
