A task management API earns its place when work begins somewhere outside your task board. A signed proposal, support request, content calendar, or staffing change can create a predictable update without asking someone to copy the same information into another system.
Sydnee's public REST API supports specific account, user, request-template, task-template, task, and read-only file workflows. It authenticates with bearer API keys, not OAuth. The examples below focus on the current Task API and the operational decisions you still need to make around it.
Use the product interface when a person is making a one-time judgment. Use the API when a verified external event should produce the same supported task action each time.
1. Add an onboarding template after a client signs
When a proposal or customer relationship management (CRM) system records a signed agreement, your integration can add an existing Task template to the matching Sydnee account.
This works best when the template already contains the standard sections, tasks, subtasks, visibility rules, and relative dates your team has reviewed. The integration supplies the event. The template supplies the repeatable work.
Do not assume that a contract event creates the Sydnee account automatically. First retrieve or create the account through the supported account endpoints, then use the current Task-template endpoint for that account.
2. Create a client-assigned task
Some work belongs to the client: approve copy, upload a missing asset, or confirm a launch date. The API can create a client-visible task and assign an eligible portal user.
The current create-task contract accepts one assignee. A portal user can be assigned only when the task is visible to clients. Whether that client can edit or complete the task depends on the task's client-access settings.
This TypeScript example creates one visible task. Replace the sample identifiers with values returned by the API.
const apiKey = process.env.SYDNEE_API_KEY;
if (!apiKey) throw new Error("Missing Sydnee API key");
const accountId = "acct_123";
const boardId = "board_cuid_17";
const portalUserId = 1234567890;
const taskPath =
`/v1/accounts/${accountId}/task-boards/${boardId}/tasks`;
const response = await fetch(`https://public-api.sydnee.app${taskPath}`, {
method: "POST",
headers: {
Authorization: `Bearer ${apiKey}`,
"Content-Type": "application/json",
},
body: JSON.stringify({
title: "Approve homepage copy",
assigneeUserIds: [portalUserId],
clientAccess: { visibleToClients: true, editableByClients: true },
}),
});
if (!response.ok) throw new Error(await response.text());The live OpenAPI specification is the authority for request schemas and response fields.
3. Apply a campaign checklist across selected accounts
A service rollout may require the same kickoff structure for several clients. Your integration can list the selected accounts and add a reviewed Task template to each one.
Keep the selection rule outside Sydnee explicit. For example, your CRM might identify accounts on a specific service tier. Do not loop through every account unless the business event truly applies to every account.
Record each response and retry failures individually. A partial batch should not leave your team guessing which accounts received the work.
4. Escalate overdue work by rule
The task-list response includes due information that can identify overdue work. A scheduled process can list tasks, select those that match a documented rule, and update their priority through the priority endpoint.
A useful rule might be: raise open, overdue tasks from NORMAL to HIGH after an account owner reviews the automation. Avoid turning every late task into URGENT. Priority should still communicate a real operational distinction.
The API changes the field you request. It does not decide whether an overdue task represents a client delay, an internal blocker, or a date that should be revised.
5. Move tasks after an external production event
If another system records a meaningful production state, your integration can move the related Sydnee task into the matching board section.
For example, a publishing workflow could move a task from In production to Client review after the external system confirms the review asset exists. Store the Sydnee task identifier with the external record so the integration updates the intended task.
The move endpoint accepts a destination section and position. It does not create a universal workflow engine or infer which external event should trigger the move.
6. Create repeating client work
The Task API supports repeating due-date rules for eligible tasks. Current frequencies include daily, weekly, biweekly, monthly, and yearly schedules.
Use repeating tasks for work that truly follows the same cadence, such as a monthly report review. Completing the current occurrence creates the next occurrence when Sydnee can calculate the schedule.
This is different from duplicating an entire engagement. If each cycle needs a full set of sections and tasks, apply a Task template instead of forcing one repeating task to represent the whole workflow.
7. Sync approved context into a description
The description endpoint can replace or append supported content. That makes it useful when another system holds information the assignee needs, such as a confirmed scope change or a link to an approved brief.
Only copy information that belongs in the client task. Avoid treating every CRM note, email, or call transcript as task context. A focused summary is easier to act on and less likely to expose unrelated information.
8. Post structured task comments
Comments work well for timestamped updates that should remain separate from the main description. An integration can post a comment after an external review finishes, then retrieve the comment thread when another approved workflow needs that context.
Use a consistent comment format that names the source event and the resulting state. Do not present API-created comments as human approval unless a person actually made and recorded that decision.
9. Reassign open work during an account handoff
When account ownership changes, an integration can find the affected open tasks and replace the current assignee with another eligible account user.
Treat reassignment as a controlled batch:
- List tasks in the relevant accounts and boards
- Exclude completed or intentionally unassigned work
- Confirm that the new assignee has access to each account
- Update one task at a time and retain the response
- Report any task that could not be reassigned
This turns a broad staffing change into a reviewable set of task updates rather than an unverified bulk promise.
10. Let an AI agent propose task changes
An artificial intelligence (AI) agent that can call HTTP tools can use the same documented endpoints as another integration. It might summarize open work, propose overdue-task changes, or draft a comment from approved source material.
Keep a person in the loop for changes with client, deadline, or access consequences. API keys currently apply to one Sydnee workspace and the public API does not provide OAuth scopes for narrowing a key to one workflow. Store keys outside prompts and source code, validate every identifier, and log each requested mutation.
The API's consistent error responses help an integration report what failed. They do not make an autonomous action correct by default.
Current Task API coverage
The current /v1/ task surface includes endpoints for:
- Listing boards, sections, and tasks
- Creating top-level tasks and subtasks
- Retrieving task detail and activity
- Updating titles, descriptions, status, priority, due dates, assignees, collaborators, and client access
- Moving and archiving tasks
- Reading and posting comments
- Adding and removing reminder rules
- Working with supported task attachments
- Listing Task templates and adding one to an account
The public Files API is read-only at the time of this update. Do not design a Task API workflow that assumes it can upload, rename, or delete account files through the public API.
Current limits are 300 read requests and 100 write requests per minute for each authenticated API key. Handle 429 responses and the returned rate-limit headers instead of assuming every batch will finish in one pass.
Start with the contract
Create API keys in Sydnee under Company Settings → API. Send the key as a bearer credential to https://public-api.sydnee.app, and use the current API reference or OpenAPI document for exact schemas.
Start with one narrow automation and test it against non-sensitive sample data. Confirm account access, client visibility, error handling, and retry behavior before expanding the workflow.
For supported resources, plan context, and the difference between the API and Zapier, review Sydnee API access. The connected client portal workflow shows where Tasks fit around Requests, Files, chat, and delivery. If you need to evaluate a multi-system workflow with the team, book a Sydnee demo.
