API Documentation: [login to view URL]~1data-plans-for-esimdb/get

Important Note: I previously hired someone (https://www.freelancer.com/u/pablomontoro040
) who failed to complete this project, and I lost 2 months. Therefore, I will only consider true experts with proven experience in API integrations and preferably telecom/eSIM platforms. If you are not highly experienced, please do NOT apply.

Requirements:

Strong experience with API integrations (REST/JSON).

Ability to map our product schema to the eSIMDB schema (validity, dataCap, dataUnit, prices, coverage, telephony, subscription, tethering, etc.).

Error handling, retries, and clean, well-documented code.

Experience with sync jobs to keep listings up-to-date.

Clear milestones and ability to demonstrate working integration in a staging environment.

Application Instructions:
When applying, please include:

A short summary of similar API integrations you have completed (with links/screenshots if possible).

Your proposed approach for mapping our eSIM plans into the eSIMDB schema.

Estimated timeline and fixed-price offer (with milestones).

Links or references to past relevant work.

Only serious, qualified professionals will be considered. Thank you." (client-provided description)
