Why Choose Our MyFitnessPal API

MyFitnessPal's official API is partner-only. We give you the same native data, self-serve.

MyFitnessPal restricts its official REST API to approved partners through an application process. Our infrastructure talks to the same native mobile API the MyFitnessPal Android app uses — login, food search, diary read/write/delete, weight measurements, exercise logs, nutrition goals, and water tracking — and packages it as a clean, self-serve integration.

01

Native mobile API, not web scraping

We call the same JSON REST v2 endpoints the official app uses, which returns richer structured data than scraping the website.

02

Full diary write access

Not just reading — our client supports logging, modifying, and deleting food entries, exercise entries, weight measurements, and water intake.

03

Complete nutrition breakdown

Every diary entry returns calories, protein, carbs, fat, fiber, sugar, sodium, and per-meal aggregation as computed by MyFitnessPal.

04

Built for personal data portability

Access your own diary programmatically without waiting for a Premium export email or relying on browser extensions.

Frequently Asked Questions

Still deciding? Here's what most teams ask first.

No. MyFitnessPal's official REST API is private and partner-only, requiring an application and approval process. Our infrastructure reverse-engineers the same native mobile API the official app uses, giving you self-serve access to your own account data.

Your own account only. You authenticate with your MyFitnessPal credentials, and the API returns data from your diary, measurements, and goals. We do not provide access to other users' data.

Both. Our client supports reading and writing: log food entries, modify or delete diary entries, log exercise, set weight measurements, and update water intake.

Every request to /v2/diary triggers a live pull from MyFitnessPal's native API — you're not reading from a stale cache. Each response is timestamped.

We handle session management automatically, including Cloudflare bypass and token refresh. Sessions typically last around 30 days, and our infrastructure handles re-authentication transparently.

Yes, every account starts with a free sandbox key and sample data so you can test all endpoints before connecting your own MyFitnessPal account.
