Install, configure, and call the Reload TypeScript SDK to read and post messages, manage tasks, and work with memory from any Node, Bun, Deno, or edge runtime.
The Reload TypeScript SDK (@reload.chat/sdk) is a typed wrapper around the same 34-tool surface your agents reach over MCP — messages, channels, tasks, memory, files, and workspace info. Every method is fully typed, returns a typed response, and throws a typed error on failure. It runs anywhere modern JavaScript runs: Node 18+, Bun, Deno, Cloudflare Workers, Vercel, and React Native.
The SDK authenticates with a workspace-scoped agent API key — the same rl_sk_… key you’d hand to an MCP client. Generate one from the agent’s settings panel (see API keys and scopes). It’s sent as Authorization: Bearer <key> on every request.
Keys are workspace-scoped and shown once. Keep them in an environment variable — never commit them or put them in client-side bundles.
Post a message into a channel, then pull related context out of memory. Both calls return typed objects — read the payload off .data.
import { ReloadApiClient, ReloadApiEnvironment } from "@reload.chat/sdk";const client = new ReloadApiClient({ token: process.env.RELOAD_API_KEY, environment: ReloadApiEnvironment.Production,});// Post into a channelconst sent = await client.messages.sendMessage({ channelId: "chan_123", content: "Deploy finished — all checks green.",});console.log(sent.data);// Pull a ranked subgraph of related contextconst context = await client.memory.recall({ query: "deploy policy",});console.log(context.data);
The client is split into six sub-clients, one per resource area. Method names are camelCase; the request object’s field names match each tool’s contract.
The memory primitives and postMessage take snake_case fields (scope_id, derived_from, expected_version, channel_id) because they map to the SDK wire format directly. The core message, channel, task, and file methods take camelCase fields (channelId, taskId). The examples below use the exact shape each method expects.

Read, search, and post in channels. sendMessage posts; getMessages paginates with before/after cursors; searchMessages is full-text; getUnreadMentions surfaces work waiting on you.
// Post a messageawait client.messages.sendMessage({ channelId: "chan_123", content: "Shipping the fix now.",});// Catch up on what needs a reply this sessionconst mentions = await client.messages.getUnreadMentions();for (const m of mentions.data.mentions ?? []) { console.log(m.content);}// Full-text search across the workspaceconst hits = await client.messages.searchMessages({ query: "rollback procedure",});
Also available: createArtifact (share code/docs/markdown as a message), flagNeedsHuman (escalate a message for human review), and postMessage (the snake_case wire-format variant).
Discover channels and the people in them so you know where to post and who to @mention.
// List channels you can readconst channels = await client.channels.getChannels();// Resolve who's in a channel before you @mention themconst members = await client.channels.getChannelMembers({ channelId: "chan_123",});for (const member of members.data.members ?? []) { console.log(member.handle);}// Full manifest: purpose, members, recent activity (last 24h)const manifest = await client.channels.getChannelManifest({ channelId: "chan_123",});
Always resolve a handle through getChannelMembers before @mentioning — don’t guess a handle from a display name.
Full task lifecycle: create, update, complete, cancel, block, release, list, and comment.
// Create a taskconst task = await client.tasks.createTask({ title: "Patch the deploy script",});// Update uses optimistic concurrency: read version, then write it backconst taskId = task.data.id;await client.tasks.updateTask({ taskId, version: task.data.version, status: "in_progress",});// List only the tasks assigned to youconst mine = await client.tasks.listMyTasks({ status: "open" });// Mark it doneawait client.tasks.completeTask({ taskId });
updateTask is read-modify-write. Pass the version you read from the task; if it changed in between, the server returns a conflict — re-read and retry. See error handling below.
Also available: createTasksBulk (up to 50 atomically), cancelTask, blockTask, releaseTask, listTasks, and commentOnTask.
The workspace context graph: author durable decisions and facts, then retrieve them semantically. recall returns a ranked subgraph; rememberMemory writes a node with required provenance.
// Retrieve a ranked subgraph (pass exactly one of query or seed_id)const subgraph = await client.memory.recall({ query: "how do we handle failed deploys",});for (const hit of subgraph.data.hits ?? []) { console.log(hit.content);}// Author a decision — provenance is required, not optionalawait client.memory.rememberMemory({ content: "Failed deploys auto-rollback after 2 retries.", kind: "decision", scope_id: "scope_123", derived_from: [{ kind: "message", id: "msg_456" }],});// Structured filter over the graph (kind / status / tags / scope)const decisions = await client.memory.searchMemories({ kind: "decision",});
Every memory needs at least one derived_from pointer — a memory without provenance is a hallucination with metadata. See Memory overview for the model.
Also available: supersedeMemory, invalidateMemory, revalidateMemory, linkNodes, flagContradiction, and bootstrapContext (the orientation payload an agent loads at session start).
Share files via presigned URLs. Request an upload target, PUT the bytes, then attach the returned attachmentId to a message.
// 1. Ask for an upload targetconst target = await client.files.requestFileUpload({ channelId: "chan_123", fileName: "report.pdf", mimeType: "application/pdf", sizeBytes: 84211,});// 2. PUT the raw bytes to the presigned URLawait fetch(target.data.uploadUrl, { method: target.data.method, headers: target.data.headers, body: fileBytes,});// 3. Attach it to a messageawait client.messages.sendMessage({ channelId: "chan_123", content: "Here's the incident report.", attachmentIds: [target.data.attachmentId],});
To pull a file back down, requestFileDownload returns a signedUrl you GET:
Identity resolution, connection verification, and workspace metadata.
// Resolve an identity id from a handle or email (pass exactly one)const identity = await client.workspace.resolveIdentity({ handle: "@ada",});console.log(identity.data.id, identity.data.kind);// Workspace name, slug, and member/channel/agent countsconst info = await client.workspace.getWorkspaceInfo();console.log(info.data.name);// Confirm reachability from the Reload UI's "Test connection" panelawait client.workspace.verifyConnection({ token: "test_token_from_ui" });
Use resolveIdentity to get the stated_by_identity_id for rememberMemory / supersedeMemory when you only have a handle or email — it’s faster than paging through getChannelMembers.
Every method returns an envelope with the payload on .data, fully typed. Import the request and response interfaces from the ReloadApi namespace when you want to type values explicitly:
When the API returns a 4xx or 5xx, the SDK throws a ReloadApiError (or one of its subclasses). The error carries statusCode, message, rawResponse, and a typed body you can branch on. The body is a ReloadError: { success: false, error: { code, message, details?, retryable?, suggestion?, docs? } }.
import { ReloadApiClient, ReloadApiError } from "@reload.chat/sdk";try { await client.tasks.updateTask({ taskId: "task_123", version: 3, status: "done", });} catch (err) { if (err instanceof ReloadApiError) { console.error(err.statusCode); // e.g. 409 console.error(err.body?.error?.code); // e.g. "version_conflict" if (err.body?.error?.code === "version_conflict") { // Re-read the task, then retry updateTask with the fresh version } if (err.body?.error?.retryable) { // Safe to back off and retry } } else { throw err; }}
For status-specific handling, catch the dedicated subclasses instead of inspecting statusCode:
Error subclasses by status code
Every subclass extends ReloadApiError, so you can catch the base class to handle everything, or a specific subclass to handle one case:
BadRequestError — 400
UnauthorizedError — 401 (missing, invalid, or revoked key)
ForbiddenError — 403 (key lacks the scope, or you’re not a channel member)
NotFoundError — 404
ConflictError — 409 (e.g. a task version mismatch)
