The Mexican marketplace: pesos, Spanish and a local tax identity
Of the four regions, Walmart Mexico has the most pronounced localisation requirements. Product content is expected in Spanish, prices run in Mexican pesos, and on the seller side the question of a local tax identity comes up. These are not technical settings of the connection — they are commercial prerequisites to settle before it is set up.
The technical side is identical to the other regions: a client ID and secret from the developer portal, plus the partner identifier where required. The keys are again region-specific.
