Integrations
Calling Sume from automation platforms, serverless functions, agent frameworks, and MCP clients. Each uses plain HTTPS or remote MCP, not a connector.
Can DeepSeek V4.1 Flash call Sume's hosted MCP tools?
DeepSeek V4.1 Flash supports tool calls. Your code maps each call to Sume MCP tools_list, tools_schema and a gated paid call. The model never holds your key.
Threads topic tag: 1 to 50 characters, no periods or ampersands
Meta's Threads API accepts a topic tag of 1 to 50 characters and rejects periods and ampersands. Validate the tag in code before you publish a Sume clip.
Pinterest bulk upload: 200 Pins per CSV with Sume media URLs
Pinterest bulk creation takes up to 200 images or videos per upload from a CSV with Title, Media URL and board. Fill the Media URL column from Sume renders.
X media upload APPEND: 5 MB chunks, and how to split a Sume MP4
The X API v2 APPEND step takes chunks of at most 5 MB. Count the segments for a Sume MP4 with a short script before you upload to the initialize endpoint.
Threads link limit: 5 unique URLs per post, checked before publish
Threads allows 5 unique URLs per post and returns THREADS_API__LINK_LIMIT_EXCEEDED past that. Count unique links in the caption before posting a Sume clip.
Calendly webhook signature t= v1= with 3 minutes vs Sume sume-v1
Calendly sends t=<ts>,v1=<sig> signed over t.body and suggests 3 minutes of tolerance. Sume signs timestamp.body as sume-v1; write a separate check for each.
Ghost audio card with a Sume track: mp3, wav or ogg from desktop
Ghost's audio card takes .mp3, .wav and .ogg uploaded from the desktop editor, up to 1 GB by plan. Download the Sume artifact, then upload the file.
GITHUB_STEP_SUMMARY for Sume jobs: an audit table in the run page
Write the Sume job id, status and artifact URL to GITHUB_STEP_SUMMARY: 1 MiB per step, 20 step summaries shown per job. Public URLs only, no prompts or keys.
workflow_dispatch music brief: 25 inputs, 65,535 chars vs Sume's 5,000
GitHub dispatch takes 25 inputs and 65,535 characters; Sume's music prompt stops at 5,000 and rejects duration. Guard the length, then call the router.
Make webhook 429 at 300 requests per 10 seconds and Sume retries
Make returns 429 above 300 webhook requests per 10 s. Sume retries a non-2xx up to 10 times, 30 s apart, so a short burst clears; your own replay loop does not.
One Make webhook for Sume job.completed and format.run.terminal events
Sume sends job.completed for model jobs and format.run.terminal for Format runs, with one signature scheme. Branch on event, then on outcome, and dedupe by id.
Make's Accepted 200: why Sume won't retry a failed scenario
Make answers 200 Accepted as soon as the webhook is queued, so Sume sees success even if the scenario later fails. Reconcile by job id and use Redeliver.
Mattermost incoming webhook for Sume jobs: markdown, 16,383 chars
Post a Sume job result to Mattermost with an incoming webhook: text is markdown, attachments sit at top level, and posts up to 16,383 characters are supported.
Notion audio block from a Sume music URL: the extension check
Notion's external audio block lists .mp3, .wav, .ogg, .oga and .m4a. Check that the Sume artifact URL path ends in one; if not, use Notion's File Upload.
Slack slash command for music: 3 s ack, 5 replies in 30 min
A Slack command must be acknowledged in 3 s; response_url then allows 5 replies in 30 min. Start the Sume music job in webhook mode and reply when it lands.
Slack Workflow webhook trigger: flatten a Sume result, no nested JSON
Slack's webhook-started workflows take up to 20 flat variables and 1 request per second. Flatten Sume's nested artifacts into plain text values before you post.
Tally webhook to a Sume music job: verify, dedupe, return 200 fast
Tally signs with base64 HMAC-SHA256, waits 10 s and retries up to a day. Verify the signature, use eventId as the Idempotency-Key, then start the Sume job.
Telegram sendAudio for a Sume track: URL 20 MB, upload 50 MB
Telegram can fetch a sendAudio file from a URL up to 20 MB, or accept an upload up to 50 MB. Pass the Sume artifact link first; upload only as a fallback.
Typeform webhook auto-disabled: answer 2xx before calling Sume
Typeform disables a webhook that fails every try, and a 404 or 410 stops it at once. Answer 2xx first, then start the Sume job from a queue.
Webflow Assets API lists no audio types: where a Sume track goes
Webflow's asset docs name image, document and Lottie types, not audio. Keep the Sume mp3 on its media.sume.com URL and store that link in a CMS Link field.
WordPress media_handle_sideload for a Sume music mp3 attachment
Download the Sume artifact URL with download_url(), then media_handle_sideload() it into the Media Library. It returns an attachment id or a WP_Error.
Zendesk vs Sume webhook signatures: base64 no dot vs hex with a dot
Zendesk signs base64(HMAC-SHA256(timestamp + body)) with no separator; Sume signs timestamp.body as sume-v1 hex. One verifier cannot check both.
jobs_wait defaults to 50 seconds: how many calls for a long render
Remote MCP jobs_wait waits 50 seconds by default and 55 at most. A render that takes N minutes needs about N x 60 / 50 calls on the same ids. Never resubmit.
MCP agent: trim, then captions? video-captions create is not listed
On Sume's hosted MCP, video_trim is a listed tool but captions are not creatable from tools_list. Use the REST endpoint for the burn step in an agent chain.
fal lists Seedream 5.0 and Krea 2: find what Sume's image catalog has
fal.ai/models names GPT Image 2.5, Flux 2, Nano Banana 2, Ideogram 4, Krea 2 and Seedream 5.0. A Python check of which names appear in Sume's /v1/images/models.

Mastra 1.71 can start a tool once its own arguments are complete. For paid Sume generation that means a stable idempotency_key and a dry run before any spend.
LangGraph interrupt or wait: resume a graph from a Sume webhook
A LangGraph interrupt is for a human decision, not a video render. Pause for approval, then resume the graph from a signed Sume webhook keyed by job_id.
Mastra 1.72 crash recovery and leases: checkpoint the Sume job id
Mastra 1.72 adds multi-worker task leases and crash recovery. Store the Sume job id before waiting so a recovered worker polls instead of paying twice.
n8n 2.41.6 task runner and a Sume webhook verifier that never throws

Cursor's Auto-review classifier can allow a call you would block. For paid Sume tools, rely on server-side dry_run, max_spend_usd and OAuth scope.
Cursor Run Everything mode: a read-only Sume token is the guardrail
In Run Everything, Cursor runs every tool call without review. Connect Sume with mcp:read so paid and write tools are not even visible.
