Retrieving LLP Details

Is it possible to get Limited Liability Partnership details with the REST API? I tried using an LLP’s number to get a company profile but that didn’t work.

The getCompany API does indeed work for retreiving LLP details. Make sure you have an 8 digit company number (include the OC prefix).
Try running this command to test:

curl -u {apiKey}: https://api.company-information.service.gov.uk/company/{llpCompanyNumber}

for example running it with company number set to OC353677 yields this response:

Thanks, it’s working now. I didn’t realize the company number had to be 8 digits. :man_facepalming:
