Rest api expert needed for integrating to event booking system

Hi,
Client uses Priava which is an event booking system and has an api: https://www.priava.com/resources/priava-api/sdk_reference/rest-api/opportunities/#post-opportunity

They have enquiry forms on their website and want to integrate with Priava to create an entry in the Priava system when the website form is submitted.

Api docs linked above. Website is wordpress so perhaps a plugin would help connect it all together?

Fields would be:
Contact name
Company name
Email
Phone
Location
Room
Date
Duration/time

The form already exists, just need the connection with the API

Thanks
