Wait, isn't the firewall rule more important?

Really? I didn't know CORS was the first step!

Definitely check the Cross-Origin Resource Sharing first!

I’m a bit confused. I thought outbound firewall rules were also important, but I can’t recall if they come before checking the other settings.

I practiced a similar question, and I feel like Remote Site Settings could be the right answer. It’s about allowing Salesforce to communicate with external sites, right?
JO

I'm not entirely sure, but I remember something about Content Security Policies being important too. Maybe that's the first step?
AN

I think the first thing to check is if the endpoint domain has been added to Cross-Origin Resource Sharing. That seems crucial for web components.

Ah, I remember learning about this in my Integration Architect training. The first thing to validate is the Remote Site Settings. That's where you configure the allowed external endpoints. Gotta make sure that's set up properly.

Okay, let me think this through step-by-step. First, I need to make sure the endpoint domain is added to CORS. Then I'll double-check the Content Security Policies and Remote Site Settings. Shouldn't be too hard to figure out.

Hmm, I'm not totally sure about this one. I know we need to configure some security settings, but I can't remember the exact steps. Guess I'll have to think it through carefully.

D all the way, baby! Remote Site Settings is the key to unlocking that external endpoint. It's like the secret handshake of the Salesforce world.

Hmm, I'd say A. Cross-Origin Resource Sharing. Gotta keep those origins in check, am I right? Or is that just me being paranoid?

I'm not sure, but maybe A) The endpoint domain has been added to Cross-Origin Resource Sharing could also be a valid option.
TA
Talia 1 year ago
I agree with Helene. If the callout is failing, it's likely a CORS issue, so D) makes sense.

I'm going with B. Content Security Policies. Wouldn't want any rogue scripts sneaking in and messing things up, you know?
