Get address details

Get address information based on the provided autocomplete context. The context must have the precision `address`. A HTTP status 400 response is given when the provided context does not resolve to a single address.

This method is intended to provide address information using the result context from the autocomplete method. The result of this method can be used to complete an address in an order form for example.

Required session header

Both the autocomplete and getDetails methods require a custom HTTP header named X-Autocomplete-Session to be specified. Its value should identify a single address completion session (for example, one user filling out a checkout address) and remain the same for calls to both methods. You should not generate a new session identifier for each request, or reuse the same identifier for completing more than one address.

The value should be at least 8 characters and at most 64 characters long and contain only alphanumeric characters, "-", "_" and/or ".".

For example, our Javascript library generates a new random session header value of 32 hexadecimal characters each time a new autocomplete HTML input element is created. This session header value is used for the lifespan of that element, and is passed to the server-side proxy which forwards it to the Autocomplete API as an X-Autocomplete-Session session header.

Please ensure the session header is implemented correctly. Incorrect usage of this header will lead to increased API costs for your account.

The term and context parameters

Both the term and context parameters determine what results are suggested. They must be used correctly in order to prevent bugs in your implementation. For example, when a user selects a suggestion the next set of results might not contain the desired results.

First, make sure to correctly encode your parameters.

Secondly, make sure to provide the correct term parameter for a given context.
The autocomplete provides matches based on the current input. In order to select a match and drill down further, another call to the autocomplete method should be performed. For example, a user enters a street name and then selects the top suggestion to see specific addresses for that street. For the second call to the autocomplete: specify the context of the selected match, and use the 'value' of the selected match for the term parameter. Do not modify the value, or strip off any white-space. If the term parameter does not match the specified context, the drill down will not work as intented.

Address response

The response address can be found in the address struct split into the following fields: country, locality, street, postcode, building (formatted building number and building name), buildingNumber (can be null) and buildingName (can be null). In most countries the building number can be null, usually the building name is not null in this case, but there are a few addresses where both building number and building name are null.

Address struct without number and name

"address": {
	"country": "Germany",
	"locality": "Mittenwalde",
	"street": "Gelände Märchenwiese",
	"postcode": "15749",
	"building": "",
	"buildingNumber": null,
	"buildingNumberAddition": null

Country specific data

Countries have different address information and administrative regions, any country specific information can be found in the "details" property. The data provided per country can be found here:

URL template

The REST API requires GET requests. Parameters are added to the REST resource URL, and each parameter must be URL-encoded:{context}/{dispatchCountry}

Example REST request

Retrieving /international/v1/address/bel6SVBbpsiriOTHIBOu9LISmTCTzVymIt8qTaveozBbMHLPzZPhaKDwTsP3z64fhxMDVxyuquqSVebBGFPdvNlruQet2oZxo8fuKEwzv1rDfBNRHcZwLxThfR9rovJwW7Yqu2Gu0ZPFHobgkC56R with the proper authentication would use the following HTTP Request:

GET /international/v1/address/bel6SVBbpsiriOTHIBOu9LISmTCTzVymIt8qTaveozBbMHLPzZPhaKDwTsP3z64fhxMDVxyuquqSVebBGFPdvNlruQet2oZxo8fuKEwzv1rDfBNRHcZwLxThfR9rovJwW7Yqu2Gu0ZPFHobgkC56R HTTP/1.1
Authorization: Basic 2eTpkU******…
X-Autocomplete-Session: f60c42561f8f5a6d7cc

Example response

The lookup is successful so we receive a 200 OK status in the headers:

HTTP/1.1 200 OK
Content-Type: application/json; charset=utf-8

And a JSON response in the body:
