Use INCRBY to add an integer to the value stored at a key and get the result. A missing key counts as 0, the value must be the string form of a 64-bit signed integer, and an operation that would leave that range returns an error. A negative amount subtracts, which makes it interchangeable with DECRBY. Like INCR, the update is atomic, so it is safe for counters that several clients update at once, such as adding a batch size to a running total.

Syntax

Arguments

Response

The reply reports the result of the operation. Error replies have the same shape in RESP2 and RESP3 and are surfaced as exceptions by the SDKs below.
Client libraries often decode bulk strings, maps, sets, and numeric strings into language-native values. The table describes the Redis wire reply.

Examples

TCP examples use the TLS REDIS_URL from the Upstash console. REST examples use UPSTASH_REDIS_REST_URL and UPSTASH_REDIS_REST_TOKEN.
