Reactivates a cancelled purchase invoice, which sets its status back to `active`. Send an empty object as the body. > [!NOTE] > > The SDK samples get their client from credentials your app registers once when it starts, as shown in [Authentication](https://exsited.mintlify.site/authentication.md#set-up-a-client). To try the call here, click **Try it**, set `host` to your Exsited API host name and paste an access token from [Get an access token](https://exsited.mintlify.site/api-reference/authentication/get-an-access-token.md). To send a raw JSON body instead of filling in fields, copy the cURL sample and edit its `-d` payload. ## OpenAPI ````yaml POST /purchase_invoices/{purchase_invoice_id}/reactivate openapi: 3.1.0 info: title: Exsited API version: v4 servers: - url: https://{host}/api/v4 variables: host: default: your-api-host.example.com description: Your Exsited API host name, without https://. security: - bearerAuth: [] tags: - name: Authentication - name: Accounts - name: Account emails - name: Account groups - name: Communications - name: Communication profiles - name: Orders - name: Quote orders - name: Express - name: Usages - name: Sales reps - name: Gift certificates - name: Invoices - name: Pro-forma invoices - name: Payments - name: Refunds - name: Credit notes - name: Credit note applications - name: Reconciliations - name: Items - name: Inventory adjustments - name: Units of measurement - name: Zones - name: Shipping packages - name: Shipping rules - name: Fulfillment profiles - name: Fulfillment terms - name: Item fulfillments - name: Item receipts - name: Bookings - name: Rental assets - name: Return merchandise authorisations - name: Purchase orders - name: Purchase invoices - name: Purchase payments - name: Purchase refunds - name: Purchase credit notes - name: Purchase credit note applications - name: Purchase express - name: Return vendor authorizations - name: ABA files - name: Receive terms - name: Labours - name: Tasks - name: Timesheets - name: Milestones - name: Employees - name: Departments - name: Designations - name: Teams - name: Time periods - name: Workflows - name: Workflow settings - name: Events - name: Custom events - name: System events - name: Approvals - name: Approval profiles - name: Approval user groups - name: Alerts - name: Alert responsibility settings - name: Alert responsibilities - name: Action scripts - name: Note groups - name: Note attachments - name: Instance settings - name: Accounting codes - name: Additional codes - name: Billing periods - name: Charging periods - name: Pricing periods - name: Invoice terms - name: Days of the month - name: Countries - name: Salutations - name: Document templates - name: Email templates - name: Roles - name: Operators - name: Operator groups - name: User settings - name: Custom attributes - name: Custom components - name: Custom features - name: Custom fields - name: Custom forms - name: Attribute attachments - name: Portal - name: Integration connections - name: External databases - name: Reports - name: Applications - name: Organisation - name: Child organisations - name: Webhooks paths: /purchase_invoices/{purchase_invoice_id}/reactivate: post: tags: - Purchase invoices summary: Reactivate a purchase invoice description: >- Reactivates a cancelled purchase invoice, which sets its status back to `active`.
