The START node is implicit; the root of the request must be your first action node. Every path through the tree must terminate with an **END** node. Allowed statuses: DRAFT, SCHEDULED, PAUSED. Returns 400 for any other status (e.g. IN\_PROGRESS, FINISHED). For PAUSED campaigns a safe update is performed - existing lead states are preserved and leads are remapped to compatible positions in the new sequence. For SCHEDULED campaigns the campaign reverts to DRAFT. ### Body Parameters * **campaignId** *(long, required)*: The campaign to update. * **sequence** *(PublicSequenceNodeDto, required)*: Root node of the workflow tree. ### PublicSequenceNodeDto fields * **nodeType** *(string, required)*: One of `CONNECTION_REQUEST`, `MESSAGE`, `INMAIL`, `VIEW_PROFILE`, `FOLLOW`, `LIKE_POST`, `FIND_EMAIL`, `CHECK_IS_CONNECTION`, `CHECK_IS_OPEN_PROFILE`, `SEND_LEAD_TO_INSTANTLY`, `SEND_LEAD_TO_SMARTLEAD`, `SEND_LEAD_TO_BISON`, `END`. * **unconditionalNode** *(PublicSequenceNodeDto, required for non-END nodes)*: The next node to follow unconditionally, or when a branching condition is `false`. * **conditionalNode** *(PublicSequenceNodeDto, required for branching nodes)*: The next node to follow when the branching condition is `true`. Branching nodes are `CONNECTION_REQUEST`, `CHECK_IS_CONNECTION`, `CHECK_IS_OPEN_PROFILE`, `FIND_EMAIL`. All other non-END nodes must NOT set this field. * **actionDelay** *(int, optional)*: How long to wait before executing this node, paired with `actionDelayUnit`. Range 0-100. **Recommended default for non-root nodes:** `actionDelay: 3` with `actionDelayUnit: "HOUR"` - that is the minimum the server accepts when the parent is in the list below. The resulting delay (`actionDelay` x `actionDelayUnit`) must be at least 3 hours and not more than 500 days if the parent is in the list - this applies to every node type, including `END`. Parents that require the minimum on their **unconditional** child: `CONNECTION_REQUEST`, `MESSAGE`, `INMAIL`, `VIEW_PROFILE`, `FOLLOW`, `LIKE_POST`. Parents that require the minimum on their **conditional** child: `CONNECTION_REQUEST`. The root node has no parent and may use `0`. * **actionDelayUnit** *(string, optional)*: Unit for `actionDelay`. `HOUR` or `DAY`. * **payload** *(object, conditional)*: **Schema is node-specific** - the shape of `payload` depends on `nodeType`, it is NOT a shared object. Required for action nodes that take configuration: `CONNECTION_REQUEST`, `MESSAGE`, `INMAIL`, `LIKE_POST`, `SEND_LEAD_TO_INSTANTLY`, `SEND_LEAD_TO_SMARTLEAD`, `SEND_LEAD_TO_BISON`. Not used for action-only nodes: `VIEW_PROFILE`, `FOLLOW`, `FIND_EMAIL`, `CHECK_IS_CONNECTION`, `CHECK_IS_OPEN_PROFILE`, `END`. Omitting `payload` on a node that requires one is rejected with 400 - see **Integration node errors** below. The `SEND_LEAD_TO_*` schemas are documented below; refer to the API documentation for the exact schema of the remaining node types. * **externalReference** *(string, optional)*: Your own tracking ID for this step, returned via API and webhooks. Max 100 characters. ### Integration node payloads The `payload` shapes for the three `SEND_LEAD_TO_*` nodes. All three expose the same behaviour - when a lead replies in your HeyReach campaign, they are automatically paused / removed / stopped in the external tool - but the field name differs per integration. #### `SEND_LEAD_TO_INSTANTLY` * **instantlyResourceId** *(string, required)*: GUID of the Instantly list or campaign. * **resourceType** *(string, required)*: `LIST` or `CAMPAIGN`. Must be sent explicitly - it is not defaulted. * **removeExternalLead** *(bool, optional)*: Remove the lead from the Instantly campaign when they reply in HeyReach. Applies to `CAMPAIGN` only, where it defaults to `true`. Sending it together with `resourceType: "LIST"` - even as `false` - is rejected with 400. ```json { "instantlyResourceId": "2f1a9c84-7f3e-4c2b-9d55-1b8e0a4d6c77", "resourceType": "CAMPAIGN", "removeExternalLead": true } ``` #### `SEND_LEAD_TO_SMARTLEAD` * **smartLeadCampaignId** *(long, required)*: The numeric ID of the Smartlead campaign. * **pauseExternalLead** *(bool, optional)*: Pause the lead in the Smartlead campaign when they reply in HeyReach. Always applies, defaults to `true`. ```json { "smartLeadCampaignId": 987654, "pauseExternalLead": true } ``` #### `SEND_LEAD_TO_BISON` * **bisonCampaignId** *(long, optional)*: The numeric ID of the EmailBison campaign. If omitted, the lead is created in EmailBison without being added to a campaign. * **stopExternalLead** *(bool, optional)*: Stop the lead in the EmailBison campaign when they reply in HeyReach. Applies only when `bisonCampaignId` is set, where it defaults to `true`. Sending it without a `bisonCampaignId` - even as `false` - is rejected with 400. ```json { "bisonCampaignId": 4321, "stopExternalLead": true } ``` ### Integration node errors All of the following return **400** with body `{ "errorMessage": "..." }`: * `payload` omitted on a node that requires one (`CONNECTION_REQUEST`, `MESSAGE`, `INMAIL`, `LIKE_POST`, `SEND_LEAD_TO_INSTANTLY`, `SEND_LEAD_TO_SMARTLEAD`, `SEND_LEAD_TO_BISON`): `Error in the SEND_LEAD_TO_INSTANTLY node of the campaign sequence. The required payload was not provided.` * `resourceType` and/or `instantlyResourceId` omitted: `The following properties are required: ResourceType, InstantlyResourceId.` * `smartLeadCampaignId` omitted: `The following properties are required: SmartLeadCampaignId.` * `resourceType` is not `LIST` or `CAMPAIGN`: `Error in Instantly node. The provided resource type is invalid.` * `removeExternalLead` sent with `resourceType: "LIST"`: `Error in Instantly node. Incorrect usage of the 'Remove external lead' option.` * `stopExternalLead` sent without `bisonCampaignId`: `Error in EmailBison node. Incorrect usage of the 'Stop external lead' option.` * `smartLeadCampaignId` is negative: `Error in Smartlead node. The provided campaign id is invalid.` Reference: https://docs.heyreach.io/hey-reach-api/campaigns/update-sequence ## Request ### Headers - `X-API-KEY` (string, optional) — API key header using this scheme. Example: "X-API-KEY: \{API\_KEY}" ### Body (application/json) This endpoint expects a string. - `string` ## Examples **Request** ```json "{\n \"campaignId\": 12345,\n \"sequence\": {\n \"nodeType\": \"CONNECTION_REQUEST\",\n \"actionDelay\": 0,\n \"actionDelayUnit\": \"DAY\",\n \"payload\": {\n \"messages\": [\n \"Hi {FIRST_NAME}, I'd love to connect!\"\n ],\n \"fallbackMessage\": \"Hi there, I'd love to connect!\",\n \"toBeWithdrawnAfterDays\": 30\n },\n \"conditionalNode\": {\n \"nodeType\": \"MESSAGE\",\n \"actionDelay\": 2,\n \"actionDelayUnit\": \"DAY\",\n \"payload\": {\n \"messages\": [\n \"Thanks for connecting, {FIRST_NAME}!\"\n ],\n \"fallbackMessage\": \"Thanks for connecting!\"\n },\n \"unconditionalNode\": {\n \"nodeType\": \"SEND_LEAD_TO_BISON\",\n \"actionDelay\": 3,\n \"actionDelayUnit\": \"HOUR\",\n \"payload\": {\n \"bisonCampaignId\": {{bisonCampaignId}},\n \"stopExternalLead\": false\n },\n \"unconditionalNode\": {\n \"nodeType\": \"END\"\n }\n }\n },\n \"unconditionalNode\": {\n \"nodeType\": \"END\",\n \"actionDelay\": 3,\n \"actionDelayUnit\": \"HOUR\"\n }\n }\n}" ``` **SDK Code** ```python import requests url = "https://api//api/public/campaign/UpdateSequence" payload = "{ \"campaignId\": 12345, \"sequence\": { \"nodeType\": \"CONNECTION_REQUEST\", \"actionDelay\": 0, \"actionDelayUnit\": \"DAY\", \"payload\": { \"messages\": [ \"Hi {FIRST_NAME}, I'd love to connect!\" ], \"fallbackMessage\": \"Hi there, I'd love to connect!\", \"toBeWithdrawnAfterDays\": 30 }, \"conditionalNode\": { \"nodeType\": \"MESSAGE\", \"actionDelay\": 2, \"actionDelayUnit\": \"DAY\", \"payload\": { \"messages\": [ \"Thanks for connecting, {FIRST_NAME}!\" ], \"fallbackMessage\": \"Thanks for connecting!\" }, \"unconditionalNode\": { \"nodeType\": \"SEND_LEAD_TO_BISON\", \"actionDelay\": 3, \"actionDelayUnit\": \"HOUR\", \"payload\": { \"bisonCampaignId\": {{bisonCampaignId}}, \"stopExternalLead\": false }, \"unconditionalNode\": { \"nodeType\": \"END\" } } }, \"unconditionalNode\": { \"nodeType\": \"END\", \"actionDelay\": 3, \"actionDelayUnit\": \"HOUR\" } } }" headers = { "X-API-KEY": "{{HR_API_KEY}}", "Content-Type": "application/json" } response = requests.post(url, json=payload, headers=headers) print(response.json()) ``` ```javascript const url = 'https://api//api/public/campaign/UpdateSequence';
