Convex on my lambda

I need to ingest some data to convex. how do I authenticate convex on a lambda instance? Also would I use mutation with the client from convex/browser?

import { ConvexClient } from 'convex/browser'

const client = new ConvexClient(CONVEX_URL)

await client.mutation(api.tasks.dumpData, { data })

import { ConvexClient } from 'convex/browser'

const client = new ConvexClient(CONVEX_URL)

await client.mutation(api.tasks.dumpData, { data })

Thanks

Yes "convex/browser" is appropriate for lambdas. To authenticate your mutations I would 1. set a shared secret as an env variable in both convex and lambda 2. pass it as a function argument 3. validate that the argument matches the env variable

hi thanks for the response. so I don’t need any “CONVEX PRODUCTION KEY” or anything? just my home grown auth key between the lambda and convex functions?

yep all exported mutation/query/action functions are available to anyone who has your .convex.cloud url. that's how the react client works when running in a browser, and similarly it's how your lambda can call them (contrast with internalMutation/internalQuery/internalAction, which can only be called by your own convex functions, or the convex dashboard or CLI)

Oh of course! forgot that most of the convex usecase is calling from user's client. thanks for the detailed answer @Lee !
