I want to connect a new custom launch point in my instance. However, the service I want to connect doesn't take the credentials from Marketo. I have to enter the service's credential to connect. Actually, I don't know if it's possible to do it that way in Marketo, and if so, how to do it.
Is there anybody able to help me on this?
You'll have to explain more about this provider (a lot more!). A custom LaunchPoint doesn't make automated outbound connections, it only sets up credentials for inbound connections.
If you're trying to connect to another system then you'll need to look into setting up a Webhook. This will allow you to make a call out of Marketo to another system through their API. The important thing to remember about Webhooks is that they only work in Trigger Campaigns.
Hi Hugo, our team at Salytics has products in Launchpoint, and have helped several of our clients connect Marketo to a variety of services. If you'd like, feel free to email me firstname.lastname@example.org and we can setup a call. If it's a native connection, I am happy to walk you through it at no cost, otherwise if it is something custom I can provide information on what is entailed and you can choose to hire us or do it on your own.
