A suite of endpoints for address suggestion and validation. Choose the integration path that matches your form design.
DQE offers two sets of API endpoints with equivalent functionality:
- Legacy WS - the original WS-style endpoints, still fully supported.
- RESTful - the newer REST endpoints, recommended for new integrations.
Which mode should I use?
- Use Single mode for a simple address autocomplete experience with one input field.
- Use Funnel mode when you want a guided address entry flow, usually postal code or city first, then street, then building or apartment complement.
- Use RNVP / CheckAddress when the user has already entered a full address and you need to validate or correct it.
Before implementing - Read the Integration guide → It covers common patterns, edge cases and pitfalls that apply to all endpoints. Strongly recommended.
Prerequisite - The
country field must be provided using the expected country code (three-letter ISO code). Suggestion Choose one approach depending on your form design
Single line
One free-text input. The user types freely; DQE returns suggestions in real time.
Type down
Structured fields. Each step narrows the address one level at a time.
Validation Secure all entry cases - call after free-text input or modified suggestion
CHECKADDRESS
/RNVP/ · REST: /checkaddress/
Restructures, validates and normalizes a complete address.
