* Update integrations.mdx
The first sentence in this paragraph for `### API Keys and Tokens` was missing a word or two and it wasn't entirely clear what did the original author of this docs page intended.
I've entered what seems to be the missing context but happy to re-phrase too if another wording makes better sense here.
* Made it clear that API keys are provided by you in your code
