Obtaining API key

Hello,

How do I obtain API key?

If you didn’t already (I guess not as you’re asking this question) I would definitely recommend first reading through:

a) what data you can get and the limitations eg. what the API is for (searching for specific company, officer or PSC / RLE / Legal Person detail and the documents filed which back this, primarily).

b) If you want “all the data” then use the bulk data products instead.

c) If you want to follow things in real time / keep a database of company information updated, the Streaming API may be what you need.

You can find answers to all common questions by searching this forum.
