When provided: - The same request can be safely retried multiple times - Duplicate requests return the same response with `Idempotent-Replayed: true` - In-progress requests return HTTP 409 with `Idempotent-Replayed: false` - Failed requests return HTTP 412 with `Idempotent-Replayed: false` - Reusing a key with a different request payload returns HTTP 422 - Idempotency keys expire after 24 hours version: 2.0.0 contact: email: support@ahasend.com license: name: MIT identifier: MIT servers: - url: https://api.ahasend.com description: Production server security: - BearerAuth: [] tags: - name: Utility description: Utility endpoints for health checks and diagnostics - name: API Keys description: Manage API keys for authentication and access control - name: Domains description: Manage sending domains - name: Messages description: Send and manage transactional messages - name: Accounts description: Manage account settings and members - name: Suppressions description: Manage email suppressions - name: Routes description: Manage inbound email routing - name: Webhooks description: Manage webhook notifications - name: SMTP Credentials description: Manage SMTP authentication credentials - name: Statistics description: Access transactional email statistics - name: Message Events description: Webhooks for outbound message delivery events - name: Suppression Events description: Webhooks for suppression list changes - name: Domain Events description: Webhooks for domain configuration issues - name: Route Events description: Webhooks for inbound email routing paths: /v2/accounts/{account_id}/domains/{domain}: put: tags: - Domains summary: Update Domain description: >- Updates DNS domain settings such as custom subdomains and DKIM rotation interval. operationId: updateDomain parameters: - name: account_id in: path required: true description: Account ID schema: type: string format: uuid - name: domain in: path required: true description: Domain name schema: type: string requestBody: required: true content: application/json: schema: $ref: '#/components/schemas/UpdateDomainRequest' responses: '200': description: Domain updated successfully content: application/json: schema: $ref: '#/components/schemas/Domain' '400': description: Bad request content: application/json: schema: $ref: '#/components/schemas/ErrorResponse' '401': description: Unauthorized content: application/json: schema: $ref: '#/components/schemas/ErrorResponse' '403': description: Forbidden content: application/json: schema: $ref: '#/components/schemas/ErrorResponse' '404': description: Domain not found content: application/json: schema: $ref: '#/components/schemas/ErrorResponse' '500': description: Internal server error content: application/json: schema: $ref: '#/components/schemas/ErrorResponse' security: - BearerAuth: - domains:write x-code-samples: - lang: go label: AhaSend Go SDK source: | package main import ( "context" "fmt" "log" ahasend "github.com/AhaSend/ahasend-go" "github.com/AhaSend/ahasend-go/api" "github.com/AhaSend/ahasend-go/models/requests" "github.com/google/uuid" ) func main() { // Create API client with authentication client := api.NewAPIClient( api.WithAPIKey("aha-sk-your-64-character-key"), ) accountID := uuid.New() // Create context for the API call ctx := context.Background() // Update domain settings response, httpResp, err := client.DomainsAPI.UpdateDomain( ctx, accountID, "example.com", requests.UpdateDomainRequest{ TrackingSubdomain: ahasend.String("click"), ReturnPathSubdomain: ahasend.String("mail"), DKIMRotationIntervalDays: ahasend.Int(45), }, ) if err != nil { log.Fatalf("Error updating domain: %v", err) } fmt.Printf("Status: %d\n", httpResp.StatusCode) if response != nil { fmt.Printf("Updated domain: %s\n", response.Domain) } } components: schemas: UpdateDomainRequest: type: object properties: tracking_subdomain: type: string description: >- Optional custom tracking subdomain.
