Workflow guides updated: November 12, 2026. Checked-in campaign reference: original contract snapshot September 30, 2026.
Shuffll Engage — Personalized video at scale — is the product. The flat-video-v1 campaign workflow documented here is one API rendering format. Its restrictions must not be interpreted as a product-wide statement that Engage cannot personalize videos.
The reference describes the documented V1 operation contract. Live access depends on workspace entitlements, scopes, tenant policy and hierarchy. Read capabilities_get and discover the live MCP tool catalog for your authorized workspace; the static reference is not an exhaustive inventory of every Engage workflow or a guarantee of access.
This reference covers workspace management, branding, membership, invitations, access and credentials, owned image uploads, configured catalogs, published-template discovery, V1 campaign orchestration, recipients, explicit generation, results, analytics and jobs.
| Workflow | Documentation | Contract to use |
|---|---|---|
| Creative authoring, scene media and review | Agentic journeys | Current journey tool schemas exposed to your authorized connection |
| Product inputs and editable artwork | Catalogs, overlays | Current source, personalization and artwork contracts |
| Published-template REST campaigns | Campaign workflows | The checked-in REST reference |
| Render counts and campaign results | Analytics | Documented campaign analytics and result operations |
| Delivery and viewer measurements | Analytics guide | The configured delivery/player analytics surface, separately from render counts |
Journey guides describe implemented Creator/Reviewer workflows and advertised development tool contracts. Their inclusion documents the capability and integration pattern; it does not certify that every production workspace exposes them. Confirm production access and the actual schema for the deployment you will use. The REST download remains its documented campaign snapshot and does not silently acquire every journey operation described in the guides.
The legacy flat-video-v1 generation operation renders frozen video clips. Storing recipient names, contact details or audience membership does not alter those clips. This operation does not perform behavior-based video variation, template authoring, product-video rendering or message delivery. These restrictions belong to this operation and format.
For personalization, confirm the actual supported journey or template inputs, data mappings and output behavior for your workspace. For delivery or external integrations, confirm the relevant operations and channel configuration separately. A successful capabilities read or a listed tool alone does not prove completed rendering or delivery.
This page does not certify general production availability of workflows outside the documented contract. For deployment and access details, contact Shuffll with your intended workflow. Marketplace submission, approval and public listing are separate from service access.
MCP clients should use the authorization discovery metadata advertised by the MCP endpoint; the original September snapshot's OAuth-off statement is superseded by discovery on the hosted service. Client support and granted scopes still determine access.
Uploaded images support PNG, JPEG and static WebP, up to 10 MiB. Promoting an owned verified branding image is an explicit publication action; private originals remain private. Published branding is durable and V1 has no unpublish operation. Refer to the API's upload lifecycle before using it.
Discover transition availability through catalogs_transitions for the selected workspace. Use only returned native styles and their documented scene restrictions; a style is offered only after the same immediate effect works in interactive playback and final MP4 rendering. Do not infer transition availability from an old empty catalog response or a schema field. No generated or FFmpeg transition fallback is offered.
The Shuffll Video Production API is documented separately. Use its own features, credentials and endpoints when integrating video projects.
