Edit a Template
Updates an existing Template by its ID or name.
https://api2.transloadit.com/Updates the Template represented by TEMPLATE_ID_OR_NAME. Omitted top-level settings remain
unchanged, so the request example below renames the Template without changing its Instructions.
Supplying template replaces the stored Instructions in full; it does not merge or patch
individual Steps. Include every Step and Instruction you want to keep in that object.
Request example
Set TEMPLATE_ID_OR_NAME to your resource value without percent-encoding it.
Run this request in a server-side shell with curl and a suitable bearer token in TRANSLOADIT_TOKEN. If you need a token, expand the setup below.
Need a bearer token?
In a trusted server-side shell with curl and jq, set TRANSLOADIT_KEY and TRANSLOADIT_SECRET to your Auth Key and Auth Secret. Keep both credentials and the resulting token secret; never run this setup in browser code.
First, create a token with this endpoint’s required scopes. Your Auth Key must already grant those scopes.
if ! TOKEN_RESPONSE="$(curl --fail-with-body -sS \
--request POST \
--url 'https://api2.transloadit.com/token' \
--user "${TRANSLOADIT_KEY:?Set TRANSLOADIT_KEY}:${TRANSLOADIT_SECRET:?Set TRANSLOADIT_SECRET}" \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'grant_type=client_credentials' \
--data-urlencode 'aud=api2' \
--data-urlencode 'scope=templates:write')"; then
printf '%s\n' "$TOKEN_RESPONSE" >&2
exit 1
fi
TRANSLOADIT_TOKEN="$(printf '%s' "$TOKEN_RESPONSE" |
jq -er '.access_token | strings | select(length > 0)')" || exit 1
Keep this shell open and run the request below. Reuse the token while it remains valid.
curl --fail-with-body -sS --request PUT \
--url "https://api2.transloadit.com/templates/${TEMPLATE_ID_OR_NAME:?Set TEMPLATE_ID_OR_NAME}" \
--header "Authorization: Bearer ${TRANSLOADIT_TOKEN:?Set TRANSLOADIT_TOKEN}" \
--data-urlencode 'params={"name":"resized-images"}'
Authentication
This endpoint accepts signed params or a bearer token. See Authentication for setup instructions.
Required scope for the Auth Key or bearer token: templates:write.
Signed requests require both a signature and a future params.auth.expires timestamp. Bearer tokens do not require either.
Path parameters
templateIdOrName(path segment), required. pattern:^[a-z0-9-]+$, minimum length: 1
Form fields
Content type: application/x-www-form-urlencoded
params(JSON string), required. A JSON-encoded object whose supported keys are listed below.signature(string). Required for signed requests. Omit this field when using a bearer token.
Supported keys inside the params field
Authentication fields in this list apply to signed requests. With a bearer token, you can omit params.auth and the separate signature field. Compare the authentication-specific request parameters below.
