Frum.Finance

I may need someone to help me set up a system in which a lambda from slackapp (slack_admin) can trigger a lambda from frumfinancecore (respond_slack_lambda) because I am not sure how that is done

There are multiple existing examples. <@U07R37X01EJ> can you point to one?

rn we just exposed a rest api and granted the slackapp access to invoke the resource in apigw

that’s the existing pattern and you can add routes there in theory.

Alternatively you can invoke it directly with a similar auth pattern

<@U07R37X01EJ> That wont work here. The reason we need two lambdas is because one of them needs to return quickly and the second one will be a longer task.

so the first one can't wait for the second one to execute before it returns a result

Have lambda 1 put a message onto the queue that lambda 2 is subscribed to, then return

<@U07E8MGUWCE> it shouldn’t matter.

we can have 1 sqs fifo queue and a lambda receiving messages. The message body contains message and slack id.

the handler just sends the message

so we can share this lambda in the whole app

yeah that all makes sense. I don't really know how to set anything up. Anything I setup inside AWS is only if I copy paste it from somewhere else in the codebase.

so it shoudn't be like copy pasting magic

we have examples of making queues in budgetinsightsstack (unless it’s in stateful stack, don’t remember)

yes I think so. My point is I need existing examples to work off of. Do we have such examples for this?

for sqs to lambda? you can google cdk sqs to lambda

we also have event bridge trigger already set up if you want an example

Ok I will look for all that. I happen to be especially terrible at JS/TS. But I'll figure it out. Thanks for your help!

ok sure. I will probably look in the afternoon

this is an example of granting cross account access

this is in core granting access to slack and access to anyone to call a public api

although it could be that second statement is redundant
