API file upload
Upload files from scripts, tools, and internal workflows
FileFast API access lets Plus and higher plans create scoped tokens, send files programmatically, and keep transfers in the same account workspace.
A clearer transfer
Fast to send. Simple to receive.
Token-based uploads
Generate API tokens from your profile and use them for authenticated uploads.
Transfer-first workflows
Build repeat upload flows that create one tracked transfer from an ordered file set.
Transfer-focused API
Use FileFast for file delivery rather than permanent cloud storage.
Using the API
Creating transfers from your own tooling
Scoped tokens, not your password
Tokens are created per use and can be revoked without touching your account. A script that leaks a token costs you one revocation.
Uploaded files are ordered inputs
You upload the parts, then create one transfer from them in the order you want. There is no separate file library to manage, because the transfer is the object.
Rate limits by plan
Sixty requests a minute on Free, one hundred and twenty on Plus, three hundred on Creator. Enough for scheduled delivery jobs; not intended as a storage backend.
From your own tooling
A transfer your script can create
When delivery is part of a pipeline, it should not require a browser. Scoped tokens create the same transfer your account would.
