Events in TCMB EVDS that can start a workflow.

Actions 4

What Zervanor can do in TCMB EVDS.

Categories1

GET

Get Categories

List the top-level data categories (ana konu başlıkları) in the EVDS catalog (GET /categories). Safe read that verifies the API key + connectivity. Note the EVDS quirk: the official service documents this as /categories/key=<key>/type=json; here the key is sent as the 'key' auth header and type=json is carried as a defaulted query parameter.

Datagroups1

GET

Get Data Groups

List the data groups (veri grupları) within a category (GET /datagroups). Use mode=1 with a category code to filter to one category, or mode=0 to list all groups.

SerieList1

GET

Get Series List

List the series (seriler) that belong to a data group (GET /serieList). Returns each series code, name and frequency so you can pick codes to pass to Get Series.

Series1

GET

Get Series

Fetch time-series observations (GET /series). Pass one or more series codes joined by '-' (e.g. TP.DK.USD.A-TP.DK.EUR.A), a startDate/endDate window in DD-MM-YYYY format, and optional aggregationTypes / formulas / frequency. Returns observations under 'items'. Usable as a scheduled polling source keyed on the latest observation date.
