Query Opportunities based on Contact or Lead ID

[Chandan7]

Hi All,

As per the API documentation (https://developers.marketo.com/rest-api/lead-database/opportunities/#query_fields_browse) we can query the opportunity using searchable or ID field parameter, but in the opportunity tab UI level marktoGUID & externalOpportunityId are not there then how do we get/query the opportunity related information based on either contact or lead ID?

Thanks,

Chandan
